Alex Karras

Karras struggled in the beginning at Iowa, with classwork, homesickness and with his coach, Forest Evashevski. He was a pledge at Sigma Nu fraternity during his first year in school. Karras probably would have left Iowa had he not befriended a Greek theater owner, Ernie Pannos, as well as fellow players Cal Jones and Bob Commings. Karras' sophomore year with Iowa in 1955 got off to a rocky start when he showed up for practice twenty pounds (9 kg) overweight. Karras was also hampered that season by a cracked ankle bone. After being disappointed at not getting to play in the season finale, Karras threw a shoe at Evashevski and quit the team. Karras did not earn a football letter for the 1955 season.

Karras went to summer classes and later rejoined the football team, but a strained relationship resurfaced. Evashevski promised to start Karras in the 1956 season opener against Indiana, when he would square off against his brother, Ted. But Evy played Karras off the bench instead, and Karras quit the team again. This time, Karras agreed to rejoin the team only after making Evashevski promise he would not talk to him other than in a coaching capacity. (Evashevski always denied any special agreement with Karras.) Iowa took the lead in the 1956 Big Ten title race with a 7–0 victory over Minnesota. The Hawkeyes then clinched the Big Ten title and Iowa's first ever Rose Bowl berth by defeating Ohio State, 6–0. Karras sealed the game with a sack on the game's final play.

Iowa's final regular season game in 1956 was 48–8 win at home over a struggling Notre Dame team. Karras called it his biggest college win, saying, "The Karrases have always had a rivalry with Notre Dame. The school was just sixty miles (97 km) down the road from our home and we wanted to beat 'em at anything." However, after the game, Karras got into a physical battle with Evashevski. Karras did not enjoy his trip to the Rose Bowl, either. "Pasadena was the most boring town I've ever been in," said Karras. Karras helped the Hawkeyes win the Rose Bowl over Oregon State, 35–19. He was a first team All-American in 1956

Karras spent the summer of 1957 with an American track team of Greek descent. He participated in the shot put, throwing a respectable 52 feet (16 m). In his senior season in 1957, Karras was the most dominant lineman in the nation, won the Outland Trophy, and was the runner-up in the voting for the Heisman Trophy. Karras and Ohio State tackle John Hicks (in 1973) are two of only three linemen to finish so high in the Heisman Trophy voting. (Leon Hart, a Notre Dame end, was the only lineman ever to win the Heisman Trophy in 1949.) In addition, Karras was a consensus first team All-American in 1957. Hawkeye teammate Randy Duncan said,

Before his NFL career got under way, Karras signed a contract as a professional wrestler on December 13, 1957, earning $25,000 during the six-month off-season. Karras was the tenth selection of the 1958 NFL draft, taken by the Detroit Lions. He signed with the Lions, spurning an offer from the Canadian Football League's Winnipeg Blue Bombers. He quickly became one of the dominant defensive tackles in the NFL, playing for 12 seasons (1958–1962, 1964–1970) all with the Lions.

From 1958 to 1970, the Lions were over .500 six of the 13 years, making the playoffs only once, 1970, with a 10–4 record in Karras' final year. Aside from 1970, their best years were 1962 (11–3) and 1969 (9–4–1). In 1962, the Lion defense allowed 177 points (12.6 points/game), 188 (13.4 ppg) in 1969, and 202 (14.4 ppg) in 1970; for all three years they were second-least in the NFL, thanks in large part to a tough and rugged defensive line led by Karras. He was called an "iron man" and also nicknamed "Twinkletoes" by his fans, and missed only one game due to injury in his 12 NFL seasons and his 161 games played are the fifteenth most in Lions history. He made the Pro Bowl four times, and the Hall of Fame named him a member of the 1960s All-Decade team. The Professional Football Researchers Association named Karras to the PRFA Hall of Very Good Class of 2006

Karras was married twice. In 1958, he married Joan Jurgensen, with whom he had five children. The marriage ended in divorce in 1975. He married actress Susan Clark on March 21, 1980, and they had a daughter together.

From 1960 to 1966, except for his suspension in 1963, he played next to Roger Brown, forming a formidable pair of defensive tackles, until the latter was traded to the Los Angeles Rams. After another season of controversy under new head coach Harry Gilmer, Karras was rumored to be ready to play out his option and sign with the expansion Miami Dolphins of the American Football League under his former coach Wilson. Instead, Karras signed a seven-year contract with the Lions on May 20, 1966, with Wilson stating that Karras had used the threat of signing with Miami to garner the large deal with Detroit. Despite the new contract, controversy remained, as Karras and Gilmer sparred in midseason, with the coach reportedly ready to release the veteran defensive tackle. As before, it would be the coach who would depart, with Karras's former teammate Joe Schmidt taking over. On June 4, 1967, Karras once again hinted he would retire to work at a new business venture; once training camp began, though, Karras was back with the Lions. During that preseason, he jokingly commented that he would walk back from Denver if the AFL Broncos defeated the Lions. When that actually happened, Karras backtracked and flew home on the team plane. He was still an All-Pro selection in 1967 to 1969. Despite not allowing a touchdown in the divisional round of the 1970 NFL playoffs, the Lions lost to the Dallas Cowboys 5–0, his first playoff game and his final game. After the 1971 preseason, while rehabilitating a knee injury suffered the previous year, Karras was released, ending his playing career at age 35.

On January 7, 1963, Karras's ownership in Detroit's Lindell AC Bar became a source of controversy when league officials urged him to sell his financial interests in the place because of reports of gambling and organized crime influence. After first threatening to retire rather than give it up, Karras admitted placing bets on NFL games and was suspended by the league, along with Green Bay Packers' running back Paul Hornung, for one season (1963). During his exile, Karras returned to pro wrestling, taking on such memorable characters as Dick the Bruiser. He was reinstated, along with Hornung, on March 16, 1964, by NFL commissioner Pete Rozelle. Upon returning to action in 1964, Karras once refused when an official asked him to call the pregame coin toss. "I'm sorry, sir," Karras replied. "I'm not permitted to gamble." During his first year back, player discontent with head coach George Wilson resulted in Karras asking to be traded. However, the Lions settled the issue when they fired Wilson after the 1964 NFL season.

While with the Lions, Karras acquired a reputation as a zany storyteller who would improvise tales about past lives to amuse fellow players. Karras' oddball sense of humor came to the attention of writer George Plimpton, who heard many Karras stories while training with the Lions for his book Paper Lion. When the film version of the book was made in 1968, Karras made his film debut playing himself. As in Plimpton's book, Karras delights his teammates with impromptu monologues about a fanciful past, including his marriage to Hitler. Onscreen, Karras is also shown as a slave-driving coach in a theatrical sendup. The film led to Karras' appearance on The Tonight Show. On the show, he described smashing and grinding the opponent into a fourth down. "And then the coach calls on some European soccer player. 'Oh Julian! Julian!' And this little guy comes out saying, 'I'm going to kick a touchdown!'"

His older brothers, Lou (a future member of the Redskins) and Ted (who later played with the Bears and Lions), had played at Purdue but later Ted transferred to Indiana. Because of this, Alex said, "Indiana had the inside track" on recruiting him. Shortly after he graduated from high school, three coaches from the Iowa Hawkeyes met Karras at his brother Louie's house with an airplane and flew him to Spencer, Iowa, where he remained incommunicado through the summer. Writing in the Detroit Free Press in 1971 (as reprinted in the Iowa City Press-Citizen), Karras said that "nobody knew where I was, not even my mom, although Louie told her not to worry. Obviously, Iowa came up with something, I have no intention of stirring up any mess. I'll only say that, as Louie explained it, some accommodations were made by the people at Iowa that would make things easier for the family, and so away I went. It was the beginning of some awful years."

Following his release by the Lions in 1971, he made several more appearances on The Tonight Show Starring Johnny Carson and also played a bit part in The Mary Tyler Moore Show, appearing in the farewell party scene where Rhoda moves back to New York. Karras soon began acting on a full-time basis, playing a Tennessee boy turned Olympic weightlifter named Hugh Ray Feather in 1973's The 500 Pound Jerk. He played a hulking villain who menaced Clint Walker in the ABC TV film Hardcase. A minor but memorable role came one year later in the western parody Blazing Saddles (1974): the very strong and slow-witted thug Mongo, who rode into town on a huge brahman (marked with "yes" and "no" passing signals), knocked out a horse with one punch. (Mongo was also surprisingly philosophical, stating that he was "only pawn in game of life." This line was much-quoted upon Karras' death.) In 1974 he also played the part of Lyle, a Marine saved by Hawkeye Pierce in M*A*S*H. That same year, he was quickly brought in by ABC in September to replace Fred Williamson as a commentator for the network's Monday Night Football. He served three years in that role until leaving after the 1976 season, with his most memorable comment coming in his first game, when he joked that bald Oakland Raiders' lineman Otis Sistrunk, who never attended college, was from "the University of Mars", after seeing steam coming off his head.

In 1972, Karras hosted a local weekly football program for Windsor, Ontario CBC affiliate CKLW-TV, The Alex Karras Football Show; his program generally preceded the CBC's Wednesday night CFL telecasts. In 1973, Karras made several cameo appearances on the January 8 broadcast of Rowan and Martin's Laugh-In.

In 1975, Karras appeared on MNF colleague Howard Cosell's ill-fated variety show Saturday Night Live with Howard Cosell wearing a wig (a la Mongo) and performing "Already Gone" on the beach with The Eagles who were dubbed the "Alex Karras Blues Band" due to tee-shirts the band members wore bearing that moniker.

Karras' television appearances included guest roles on Daniel Boone in the episode "The Cache", M*A*S*H in the episode "Springtime", The Odd Couple and a brief run on Match Game '75. He also signed on to play the character "Super Jock" in commercials for a line of sports action toys named Super Jock, produced by Schaper (1975). In 1977, he was cast in the lead of the TV movie Mad Bull.

In 1979, he had the role of Hans "Potato" Brumbaugh, a potato farmer, on the TV miniseries Centennial. He was known for his humorous endorsement of La-Z-Boy recliners, in an ad campaign which also featured NFL greats such as Miami Dolphins Coach Don Shula, and New York Jets legend Joe Namath. In the 1980s, Karras had memorable success in the TV sitcom Webster, playing George Papadapolis, the title character's adoptive father, in a role that showcased his softer side. His real-life wife, Susan Clark, played his fictional wife in the series; Karras and Clark produced the series through their Georgian Bay Entertainment production company. The two met in 1975 while filming the made-for-television biopic Babe for CBS.

Karras returned to acting with roles that included playing Sheriff Wallace in Porky's (in which his wife, Susan Clark, also starred), and as western settler Hans Brumbaugh in Centennial. He played James Garner's closeted gay bodyguard in the 1982 Blake Edwards' film Victor Victoria. Karras played a darker role as Hank Sully, the right-hand-man of villain Jake Wise (played by James Woods) in the 1984 film, Against All Odds. Karras' most memorable role was in the 1975 made-for-TV movie Babe, where he played the hulking ex-wrestler George Zaharias, loyally caring for his cancer-stricken wife, legendary athlete Babe Didrikson Zaharias.

In conjunction with the 100 Years of Hawkeye Football celebration in 1989, Iowa Hawkeye fans selected an all-time team. The squad featured 11 players on offense and defense, two kickers, and 15 special-mention players who received strong fan support. Karras was voted to the team as a defensive lineman. He was elected to the Iowa Sports Hall of Fame in 1977 and the College Football Hall of Fame in 1991.

Karras also worked briefly as a football coach in 2007 and 2008. He worked for the SIL as an assistant coach to Bob Lombardi. He owned an ice cream parlor in Surfside Beach, South Carolina, called The Cow.

Karras was among 3,500 former NFL players who filed lawsuits against the NFL in early 2012, over the long-term damage caused by concussions and repeated hits to the head.

On October 8, 2012, it was revealed by friend Tom McInerney that Karras had been diagnosed with kidney failure. He was treated at the Saint John's Health Center in Santa Monica, California, before being released into hospice care. After returning to his Los Angeles home with family, Karras died in the morning hours of October 10.

On December 12, 2014, the Big Ten Network included Karras on "The Mount Rushmore of Iowa Football", as chosen by online fan voting. Karras was joined in the honor by Nile Kinnick, Chuck Long and Tim Dwight.

On October 28, 2018, the Detroit Lions enshrined Karras in the franchise ring of honor along with former Detroit Lions Herman Moore and Roger Brown.

On January 15, 2020, Karras was elected to the Pro Football Hall of Fame, as a Centennial Member.

On January 15, 2020, the NFL announced Karras was selected for enshrinement in Canton.
