I was watching the Pacers/Wizards game the other day and realized how far this guy has fallen off. Dude was the #2 overall pick in 2010, supposed to save the franchise. A few years later he got traded to the Pacers for the corpse of Danny Granger, where he averaged 7 points a game for the rest of the season. In the playoffs they can't even find a way to get this guy into the starting lineup. Even though he can play SG, he's getting fewer minutes than Lance fucking Stephenson, who was taken 40th overall in the same draft.
This got me thinking: who are some other disappointments that never lived up to early promise? You could mine the sports category for days. There's the obvious Kwame Brown, a #1 overall pick who couldn't catch the ball. Tons of good college QBs: Ryan Leaf, Joey Harrington, Alex Smith, etc.
But how about outside of sports? One that comes to mind immediately is The Stone Roses. They released an amazing debut album, then followed up with a pretty shit second album, and disbanded soon thereafter. A band only having one good album isn't a unique story by any means, but based on their first album they were expected to be one of the greatest bands of the 90s.
Another that comes to mind is Paul W.S. Anderson. He made the campy-but-fun Mortal Kombat, and followed that up with Event Horizon, for my money one of the best horror films ever. Pretty much everything he's done after that has been shit. The first Resident Evil film was serviceable, but the rest have been complete shit. Based on Event Horizon, I would have expected so much more out of him.
