So who is responsible for five straight years of mediocre offense?
Ultimately, the HC.
But the history is a little more complex than that. Our O in the latter part of '06 and all of '07 was outstanding. Even in '08, with the exception of the OM game, we scored enough points to win most of the games. Heck, we even scored 21 on UF at the Swamp (more than OU did in the BCSCG vs them). No RP that year, Hatch got hurt, no one to spell JL (really tough learning curve for him), and then JJ as a true Fr. Yet we were still scoring pts.
IMO, after '08 Les installed restrictor plates on Crwoton. No more playin' it fast-n-loose. So from '09 on, we've taken a very conservative approach (note: This is not synonymous with a bad approach. It has its place and time). Play great on D and STs and let other teams shoot themselves in the foot.
A good example of this is vs AU in '10. We were all tied at 17 into the 4th qtr, got great position at our own 40 with 7:51 to play. Great position to be in.
The downside to this was seen Sat. It puts an enormous amount of strain on the D, sort of handcuffs ourselves, and when you really need something extra in the engine, it ain't there.
Where I think Les needs to consider a paradigm shift is to realize when you can play great on D/STs, you can afford to play with more risk on O.
