Throughout his early career, Kurt Warner had a hard time getting a real shot to prove himself.
At Northern Iowa, Warner didn't hit the field for the first time until his senior season, where proved to all that he had a real talent.
Still, that wasn't enough, and he went undrafted in the1994 NFL Draft. With no teams finding a real interest in the unproven quarterback, he took his talents to the Arena Football League, where he played from 1995-1997.
After a few successful years in the AFL, Warner was finally given a shot with the St. Louis Rams, but they sent him off to NFL Europe to play for the Amsterdam Admirals. He would continue to impress overseas, and the following season he was brought back to take a role on the team.
Warner was the team's backup, but was quickly inserted into the starting role after Trent Green was knocked out for the year during the 1999 preseason.
With Warner under center, he took off with the team, which earned the moniker "The Greatest Show on Turf."
During his first year, Warner threw for 4,353 yards and 41 touchdowns. The team won the Super Bowl that season, 23-16 over the Tennessee Titans.
Warner was finally released in 2004, where he would then join the New York Giants. Eventually though, he would be replaced by Eli Manning.
Following his stint with the Giants, Warner joined the Arizona Cardinals. There he would revive his career, as he took the team to the playoffs in 2008 and 2009—the first of which he took the team to the Super Bowl, only to lose the Pittsburgh Steelers.
While he only won a single Super Bowl over his career, Warner constantly fought off his naysayers, only to come through again and again when the opportunity arose.
