Last year Fred Jackson had a breakthrough year. Jackson showed promise in 2007 and 2008, but no one was sure he could maintain the same level of production for a 16 games until last year. Jarius Byrd had a relatively unexpected breakout rookie season. George Wilson also had a breakout season during which he ended up starting at SS.
Which player will have an unexpected breakout season this year? Why do you hold your opinion?
For better or worse, I listed quite a few choices.
