Imagine not having a quarterback in the first round for over 30 years. Chicago took the BYU quarterback with the No. 5 overall pick. McMahon arguably could have been the best quarterback since Luckman, and he already led the club to a Super Bowl victory at the end of the 1985 season. However, he was hit in the body by Green Bay Packers defensive lineman Charles Martin in 1986, further worsening a rotator cuff injury. He never started more than nine games in the rest of his Chicago career, which ended in the 1989 offseason after a fight with coach Mike Ditka and the property.
McMahon was traded to the San Diego Chargers, where he spent a season. In 1990, he joined the Philadelphia Eagles, where former Bears defensive coordinator Buddy Ryan was the coach. In 1991, McMahon produced an 8-3 record by replacing the injured Randall Cunningham. In 1993, he landed with the Minnesota Vikings and went 8-4. The following season, he reunited with Ryan with the Arizona Cardinals. McMahon’s last two seasons were as Brett Favre’s backup with the Packers, winning a second Super Bowl ring after the 1996 season.
