Jeff Kobernus is like a Brian Roberts, without the continuous injuries (so far. He has been injured but you get what I'm saying) . He's a gap hitter (averaged around 20 doubles in 100 something games) who can steal a lot of bases (stole 42 ('12) and 53 ('11)). He seems like he could be a great second baseman but will probably only become a utility player with us.
Espinosa's potential will interest a lot of suitors. A power bat who can steal and play great defense will put everyone on notice. I still think he'll turn it around this coming year but if we can pry something nice from a team that's interested in him, I say trade away.
