25. Vince Young
If Young’s professional career matched up with his achievements at the college level then he would be a consensus Hall-of-Famer. However, the former NFL Offensive Rookie of the Year award winner was never able to match his NCAA level for any of the other franchises he played for.
Things started out well with the Tennessee Titans but went into decline in 2010. Then the Titans traded him to the Eagles but he only started three games for Philly. After this, he never played another NFL game despite popping up on the rosters of several other franchises including the Bills, the Packers, and the Browns.
