Ryan Leaf, No. 2 Overall, San Diego Chargers, 1998
The one-time Washington State star redefined the term "bust" in his brief NFL career. He wasn't a No. 1 overall -- the Colts chose Peyton Manning -- but his spectacular decline destroyed the Chargers, who traded up with Arizona to select Leaf. In 18 starts, Leaf finished 4-14 with a 48.8 passer rating. His misadventures on the field were relatively pleasant compared to his locker-room tirades. Leaf alienated the media, teammates, water boys ... anyone unlucky enough to get in his path before he retired in 2002. (AP Photo/Kent Horner)
