15. Jim Kelly played in the National Football League (NFL) for eleven seasons and spent the entirety of his NFL career with the Buffalo Bills. He also played two seasons with the Houston Gamblers in the United States Football League (USFL). Kelly was selected by the Bills in the first round of 1983 NFL draft and was taken fourteenth overall. He chose to sign with the Gamblers instead and did not play for the Bills until the USFL folded in 1986. Employing the "K-Gun" offense, known for its no-huddle shotgun formations, Kelly led one of the greatest NFL scoring juggernauts. From 1991 to 1994, he helped guide the Bills to a record four consecutive Super Bowls, although the team lost each game. In 2002, Kelly was inducted into the Pro Football Hall of Fame, his first year of eligibility. His jersey number 12 is one of two numbers retired by the Buffalo Bills. (AP Photo)
