Actually, I am going to give you a slight disgression:
It would seem top 2b are being kept, so I'll differ just slightly
You have enough 3b on your roster and with so many stud 3b being kept throw Youk back and do this:
1b A. Gonzalez
Doing this adds ANOTHER good 3b in the first round and it will increase the odds of getting the player you really want with your pick maybe Halladay or Tulowitzki? I'd take Uggla the safe option instead of hoping for an injury-plagued season out of Utley.
