I would love to see us use a Lead Blocker next year---like a FB, like we used in Mullen's early years, Hanrahan and Hemphill.
This past year I just saw a lot of 1 RB sets and zone blocking, hoping to pull defenders out of the "box" with our 4 WRs. However even spreading the Defense out still requires your OL to win their 1 on 1 blocks and our OL usually did not win at the line of scrimmage or they only got a stalemate.
Next year we will have enough RBs on our roster to run some 2 RB sets and have a lead blocking RB---Shumpert, Dear, Lee, Williams, Hollaway, Mixon, Gibson, and Murphy. That is 8 RBs folks, ok maybe 7.5 with Dear being a part time WR. But the point is we will have a bunch of options and some combination of these guys should be able to help fix the problem.
