In an NL only league, C becomes even more shallow, no? Figure Martin, Soto & McCann are kept. You have the 4th best-hitting NL catcher on your roster already. I expect a regression in average, but even if he drops 40 pts, he's still hitting .280. If you keep Doumit, you still have picks in the first 8 rounds. If you keep Hamels, you're losing your 4th rounder and need to draft a Catcher. I'd rather keep those 8 picks and draft pitching...
But, I guess you could keep Hamels and draft a guy like Jesus Flores or John Baker...
P-Baker, Gregerson, Meche
DL - Zimmerman, Volquez
