advice on a trade?

hey all, i'm in a 12-team H2H (R,HR,RBI,SB,AVG/K,W,SV,ERA,WHIP). someone in my league proposed giving me david price, dickey, and adam laroche for kershaw and matt carpenter. my gut says i should stick it out with kershaw, but i'm giving the proposal some consideration since price is a solid sp and if laroche keeps up his stats, i may not lose much by giving up carpenter. any advice?
