I think you can certainly drop granderson. Keep on eye on guys like josh bard since I'm not a big v-tek rebound believer. I also agree bill hall is kind of week at 3B. see if you can grab an sp like a previos poster had said for him. Slot chavez into 3b or see if edwin encarnacion is on the waiver wire or a few others. I think you should be able to do a little better than chris young for bill hall. I know he fell to the 10th in my league with the same format. I guess it just depends who you like though. I also think hoffman is overvalued this year. See if you can downgrade at closer (perhaps to lidge..look at his peripherals, especially babip, he will bounce back this year) and upgrade at sp. I like the pettitte pick, he is undervalued this year. sorry about the rant.
Really like the offense, 3 solid closers is very nice, SP is obviously your weakest area...it looks like you'll be struggling for K's since none of your ptichers besides Zambrano (and Pedro when he's healthy, which he's not) get a lot of them. There's probably a couple guys in your league dying for saves right now...maybe Hoffman for a reliable, high-K SP (like a Lackey)? But overall, a pretty good team, looks like 2nd or 3rd place to me, could be 1st with a few smart trades.
