Since McLain's 31-win season, only two other pitchers have approached the 30-game milestone (Steve Carlton won 27 games in 1972 and Bob Welch also with 27 victories in 1990). With Major League Baseball moving from the four-man pitching rotation of McLain's era to five-man rotations, and with the increased reliance on relief pitchers, some observers believe that another 30-game winner may not occur because of the way the game is played today. In 1974, McLain played a season for the London Majors of the Intercounty Baseball League at Labatt Memorial Park in London, Ontario, Canada. Because of his arm problems, McLain pitched only nine innings for the Majors, but played in 14 games at shortstop, first base, or catcher, and batted .380, including hitting two homers in one game in London. McLain continued to earn side money playing the organ at clubs, including a club in suburban Detroit where former heavyweight boxing champion Leon Spinks worked as a bartender. McLain also earned quite a bit of money hustling golf, easily attracting 'marks' due to his past baseball fame. Additionally, he reportedly once accepted over $160,000 to fly a wanted felon out of the country. McLain's weight ballooned to during his post-baseball career. He was imprisoned for drug trafficking (cocaine), embezzlement, and racketeering. Tampa attorneys Arnold Levine and Stevan Northcutt, who later became a Florida state appellate judge, represented McLain before the United States Court of Appeals for the Eleventh Circuit in Atlanta. His conviction was reversed under the Racketeer Influenced and Corrupt Organizations Act in the United States District Court for the Middle District of Florida in Tampa. Between his stints in prison and rehabilitation in the mid-1980s to the early-1990s, McLain could be found on various talk radio sports shows and occasionally on panel-format sports shows on network television in the Detroit area; he also modeled Hanes underwear. He could also be found signing autographs at a metro Detroit 7-Eleven store at the corner of Mound Road and Metro Parkway in Sterling Heights, Michigan, where he was employed on work-release. After his release, he also hosted a popular daily talk radio show for a few years on Detroit talk station WXYT. McLain's oldest daughter, Kristin, 26, was killed on March 20, 1992, in a drunk driving accident. She had been living in Florida and was moving back home to Michigan when she was killed just a few miles from her parents' home.
