The good news is your stacked with pitching and speed on offence, and your power is average. The only real weak spot you have is C, because those two guys in a 2C league leave a lot to be desired. The good news is you could probably offer Slowley in a trade to upgrade to a Iannetta or Napoli type catcher.
But if you want the extra pat to out you over the top, you'll have to give up Santana, Hamels, or Peavy. Since you have all those MI, CI, and U spots available, you can get the best hitter regardless of position. Peavy or Hamels could get you a Holliday or Morneau, and Santana could land you a Teixeira type hitter. Hope this helps.http://www.fantasybaseballcafe.com/forums/viewtopic.php?t=371308
