I like your IF and Matsui.
Crisp and Taveras are not my type of players. Francoeur is in his sophomore year and has arguably holes in his swing.
But overall your offense look solid. You will score a bunch of runs with Utley, A-Rod, Peralta and Matsui.
You have enough power with A-Rod, Howard and Matsui.
You have enough RBI-potential with A-Rod, Howard and Matsui and the rest of the guys.
You have enough speed with Utley, A-Rod, Peralta and Taveras.
Your SP is a little bit thin. There's a drop off after Oswalt and Harden. Freddy Garcia, Duke, Ervin and Cabrera are nice but IMO you need a guy in front of them and behind Oswalt/Harden.
RP is OK!
I would say you need another good OFer and a third starter.
