Weeks is a tough one. Behind Gantner he's the second best 2B in team history, although you could make a case for Vina. Weeks has shown flashes of brilliance and had some awful extended slumps. Injuries were a huge problem, he's only played two full seasons. Overall, his stats are mediocre, especially when you consider that he was supposedly a can't miss, 5 tool prospect, etc. He seems to be introverted and doesn't have the fan-favorite type of personalty which doesn't help either. There are a lot of parallels with Carlos Gomez--the raw talent is clearly there but we still don't know if Gomez will maintain his success or fade like Weeks did. Ben Sheets might be the #1 disappointment for me. He had Cy Young, hall of fame stuff and after that brilliant 2004 he never could stay off the DL long enough to put together a full season. Then in 2008 he got really hot, 5 CG and 3 shutouts, and he goes down in September right when the Brewers were poised for a World Series run. Sheets never threw another pitch for the Brewers, Suppan got bumped into the playoff rotation, and the rest is history. I tend to think of the guys that never had any success in the majors in a separate category.
