OP is probably right, but don't forgot a true blocking fullback, too. I don't think Boobie fits into that mold, despite his girth. Roman is going to need extra bodies for his exotic blocking schemes, so look for them to carry one less WR (Watkins, Woods, Hogan, Easley, Goodwin, Thigpen). He seems to like 2TE sets with a blocking back. I can see Gray getting a lot more playing time as the H-back, but I think Roman will want a true FB too. That just means a more crowded backfield.
