Re: question about S.p.
I'll assume that this league you are talking about is a keeper league because you said you wanted to begin to "look towards next season". Not knowing how many keeprs you're allowed and how the player is eligible for keeper I would suggest this:
Drop Ponson immediately and pick up Sowers.
Drop Clement and pick up McCarthy if he is the best younger guy still out there. I'd take McCarthy over Pelfrey.
If it isn't a keeper league, then just drop Ponson for Sowers.
Matta = Really good
