In my paper the Star Ledger, they talked about how the Jets used a fullback on 44 plays in the game as a lead blocker on running plays.
We have Corey McIntyre who is a very physical player (two monster tackles on special teams).
Hopefully with a new commitment to run Spiller, I would like to see them put Spiller in an I-formation, give it to him 5-7 yards back and let him pick his hole. The man has moves. This would take advantage of that.
