David Carr
Carr’s place on this list is a little unfair because the former Fresno State star had great work ethic and skills. But the Texans didn’t protect him in his rookie year and he took a ridiculous 76 sacks. The quarterback’s career never recovered from this beating and he threw 65 interceptions across five seasons (via Toro Times).

The shell-shocked QB never reached his full potential in the NFL. Many draft picks arrive with a lot of potential but find themselves in bad situations. Unfortunately, this was the case for Carr because the early battering shook him. Now he goes down as one of the worst busts in Houston history.
