There's what, like 24 starts a week at C/DH/1B/RF? 5 starts go to James at C. One goes to Collins at C, two more go to Collins at DH. Jose gets 5 at 1B, 1 at DH and Palka gets 3DH and 1 RF. Cordell/Tilson get the remaining 5 starts in RF.
Collins would be the odd man out most nights but I'd still prefer him getting 15 PA a week and a big league catching start to time in AAA. Don't think he has anything left to develop down there.
