RP/MRP I do have good RP: Brandon Lyon, Huston Street, H. Bell, J. Venters, R. Tracosco
DL-J. Santana

Who should I consider keeping?
I have a trio fo good closers and with little SP it kinda upsets the apple cart a bit as far as throwing all these middling-back enders back into the draft, but pitching is a bit of a premium. What 12 should I keep? I'm at a loss. I like the team if I could just have one lockdown ace it would easily win. Trading isn't allowed right now either :(

Great offense in an NL only league... hopefully you'll be able to find that ace!
