Better OF pickup - Zobrist or Sheffield

[Captain Furtah]

I have to chose between

Zobrist
Sheff
JD Drew
B Moss
C Ross
B Gardner

Please help me and I'll help you. Preference towards playing time and slightly towards power..

[Captain Furtah]

I analyzed 3 areas; not a batting average killer, power potential and playing time (both now and later) and narrowed list to...

B Moss - May be starting to come around, not a threat to lose job
C Ross - Only Hermida in front of him for FL and has 5 tool potential
M Cuddyer - Starting now, but will he share time when Delmon comes back
JD Drew - WTF, he's not on DL yet...easy choice if I thought he would stay healthy
M Hoffpauir - Solid this week (interleague) but when Lee/A Ram come back, any room?

Please help Me!
