Warner has had a solid NFL career with more accomplishments than most people are aware of. Kurt Warner has 3 Super Bowl appearances, a Super Bowl Championship, a Super Bowl MVP, 2 NFL MVP awards (1999, 2001), and is currently 5th in all-time 300 yard games. He also has the second highest playoff QB rating of 97.3 and the most yards thrown in Super Bowl history.
All this while coming into the league when he was 27 years old. He turned the St Louis Rams into a contender and did the same thing with the joke of the NFL, Arizona Cardinals. Only the 2nd QB in league history to QB two different teams to the Super Bowl.
You're right D-Rock, he probably won't be a sure shot, but I think he definitely deserves to be in.
