The one thing I'm thinking about in conjunction with this info is roster space. So at rb, Dixon is a ST guy so if they draft someone do they have space to keep him on the active roster? Maybe a player will force them to make room, but I don't know if they would plan to draft someone in rounds 2-4 if they didn't have a roster spot available for them.
So I think you have room at OT, WR, TE, QB, DE, S.
