One would believe/hope that for the fall that at least one of the three incoming true frosh TEs (Reeves, Carrigan, Sear) will show enough in August that he will make the 2-deep ahead of a walk-on listed on the 2-deep this spring. Reeves has the size and is a 4-star recruit so he seems the most likely.
Of course, as Narduzzi said, they can always adjust the offense to put more emphasis on the wide-outs and bring in a tackle for short yardage running plays when they need the extra blocker.
I suppose they could also bring in that second tackle for blocking on a pass play and slide O'Neill over to TE; given his pass catching ability and unusually speed and quickness for a tackle.
Bottom line--It probably isn't going to be as big a hole in the offense as the current depth chart suggests.
