There have been threads on the running game issues.
It is scheme, technique and player development related. The Cincy head coach reported to their fans/sportswriters that UT uses a sprint draw blocking scheme out of a pro set offense that is meant to disguise whether the play is a run or pass. In that scheme the O-line engages and drops back a step, then steers the D-line away from the gap of the play call. The RB takes the ball later and further back in the formation as it is with a draw play and is to run to the crease that is created.
Compare this to drive blocking, which is what Bama, LSU, etc. use and UT used to do with Majors and Fulmer (except with Clawface); and with the zone blocking scheme of Kiffin and the West Coast offenses (think Shanahan's offenses at Denver).
Whether that is our coaching staff's intent or not, that is what it looks like to the opponents. So they counter successfully with gap control defenses. They can load the box with 8-9 guys if we are in a run formation, or use 6-7 guys if we are in a passing set. Regardless, they have all of the gaps covered and plenty of time to react since we hand the ball off on a delayed basis deep in the backfield, or run a toss sweep that telegraphs where the play is going. The better SEC defenses do not even need to load the box, just adequately cover the gaps. UGA effectively handled run formations with 6-7 guys. As a result, the play action pass has little effect. We could get by with it when we had Hunter because the other teams could not double cover both Hunter and D-Rogers or risk losing gap control. Without him they can single cover everyone else while giving safety help on D-Rogers and still overload the box.
Go back and look at the prior games of CDD's and watch the O-line getting knocked back or staying neutral to the line of scrimmage when run blocking. The defense neutralizes them because they hit, stand up, and hand/arm fight. There is no leverage for drive blocking. They rarely run counters, traps, etc. That shows it is not a zone blocking scheme. In zone blocking the O-line seals off a gap against any defender that attempts to get in the running lane. A lead FB or H-back is used a lot in this scheme as well as some in drive blocking schemes to clear out penetration in the assigned gap. Drive blocking sets also use 2 TE's and double team in the assigned gap with a TE or OT on the off side going after any LBs or secondary in pursuit.
Whether the staff felt that our guys were too young (likely), or too dumb (doubtful), or too slow (maybe), or too weak (maybe) to do it the other ways I do not know. What I do know is they either chose incorrectly (probably) what scheme/techniques to use, or we have some pretty sorry players (doubtful).
Be informed. Once you know the truth you do not have to drink the kool-aid of the media and the emotional.
