Keeper Trade: Polanco for Bucholz

[continent]

I was offered Clay Bucholz for Polanco. Here is my team:

Me, Offense:

Soto
Ryan Howard
Ian Kinsler
Ryan Zimmermann
Elvis Andrus
Matt Kemp
Nelson Cruz
Bobby Abreu
Alfonso Soriano
Jason Bay
Franklin Guiterrez
Adrian Gonzalez
Placido Polanco

Roy Halladay
Huroki Kuroda
Colby Lewis
Mike Leake
Derek Holland
Shawn Marcum
Ian Kennedy
Kevin Slowey
Wagner
Dotel
Street
DL: Brett Anderson
DL: Jair Jurjjens

I don't necessarily feel like I want to trade him because he offers great flexibility for those days when there aren't alot of teams playing. However, alot of my pitching is fringe and Bucholz has good upside.
