Most draft projections I have seen have Bulaga being a late first or early second round pick. I'd think it would be difficult for anyone to turn down a chance for 1st or 2nd round money. So, it seems very probable that he will enter the draft.
Assuming that both Dace and Bulaga will not be back Iowa will only return Rieff and V-man with any significant playing experience. My questions is, where does that leave the O-line in 2010?
