St. Louis Rams: 10 Greatest Undrafted Free Agents in Team History

1. Kurt Warner

The Rams don’t really get 100 percent of the credit here, as it took an unsuccessful offseason stint with the Green Bay Packers in 1994, three years with the Arena League’s Iowa Barnstormers, a stint with the Amsterdam Admirals of NFL Europe, a year as a third-stringer, and an unexpected Trent Green knee injury before the Rams were forced to throw Warner into action. Once Warner got on the field, though, it turned out to be the greatest forced decision that the Rams ever made, as he went on to quarterback them to their first and only Super Bowl victory in 1999, leading the league with a 65.1 completion percentage and 41 touchdown passes while throwing for 4,353 yards. After a prolific but injury-plagued 2000 season in which he completed 67.7 percent of his passes for 3,429 yards, Warner came back in full force in 2001 and led the Rams to another Super Bowl berth by completing a league-high 68.7 percent of his passes (a league-high 375 completions) for a league-high 4,830 yards and a league-high 36 touchdowns.

Unfortunately, injuries and conflicts with head coach Mike Martz limited Warner’s success after 2001, and he started just seven more games over the remainder of his Rams career. Still, though, Warner is arguably the most famous player in Rams history and led the franchise to a Super Bowl that they had never reached before and haven’t come close to since he left.
