David Carr
Carr was one of the most exciting prospects in 2002 after his brilliant Fresno State career. The Texans opted to make him the number one draft pick but they failed to protect him. The quarterback had so much to offer but he took an insane amount of sacks. His rookie year saw him endure a record 76-sack season.

The quarterback never hit his ceiling after this but the sacks kept piling up. In the end, he retired with 267 after one of the most disappointing careers ever. He won a Super Bowl as Eli Manning’s backup in 2011 but he should have been leading a franchise. Unfortunately, he’s one of the biggest busts in history (via SBNation).
