| Ryan Leaf is about as bad as it gets. He wasn't just a bad player, he was an all around asshole. I have a feeling the Niner's Alex Smith may turn into a huge bust, but it's too early to say that yet.
In basketball, Kwame Brown comes to mind, but he's still got some time to become a decent player. Same with Darco Milicic.
In baseball, the only one I can think of is Rick Ankiel, though aparently he's doing well as a left fielder now. |
