Chad Pennington
NFL quarterbacks don’t like playing for Gang Green as we’ve learned over the past few decades. They’re still talking about Joe Namath after he retired in the 1970s. They hoped that they turned a corner when they made Pennington their number-one pick in 2000. He was brilliant for the Marshall Thundering Herd and had an outstanding rookie season.

But two devastating injuries changed his career. He dislocated his wrist in 2002 and tore his rotator cuff in 2004. These ailments drastically reduced his capacity to throw the ball. Yes, Pennington won two Comeback Player of the Year awards but the injuries took their toll. It’s a shame because he had a high ceiling but couldn’t reach it (via SBNation).
