Which of the following is the most expendable?! WHIR

[jmlevy]

Standard 5x5 Roto, 7 keeper, 1400 IP Max

C RHernandez
1B Helton
2B Cano
3B Wright
SS Rollins
OF Berkman
OF Rios
OF Willits
UTIL Hafner, Youkilis
BN Rowand, Victorino, Winn, Baldelli(DL)

SP Bonderman
SP Sabathia
RP CCordero
RP TJones
P Turnbow
P Speier
P RSoriano
BN Verlander, Penny, Lilly, Olsen, Contreras, JJohnson(DL)

Minors squad:
1 - Phil Hughes SP NYY
2 - Nick Adenhart SP LAA
3 - Scott Elbert SP LAD
4 - Alberto Callaspo 2B ARI
5 - Dexter Fowler OF COL
6 - Trevor Crowe OF CLE
7 - Carlos Carrasco SP PHI

I am considering adding Yusmeiro Petit to my minors squad, but to do so, I would be forced to drop one of the seven players listed above. If I add Petit, I would drop Contreras and then add Jeremy Guthrie.

Any ideas? I know nothing about Elbert, Callaspo, and Carrasco...are they worth the wait?

How many teams? I don't really see Callaspo helping you out unless it's a 16+ team league...

12 team league. Is Callaspo still a few years away?
