The only part I'm on the fence with is the bolded. I agree as a whole, the offense has not improved and has actually gotten worse. But I think a lot of that has to do with the gaps left when players transferred out the first couple years - moves I and many other fans took as a good sign for the "culture," but moves that absolutely left holes. The guys stepping into the OL this year should've been 3rd and 4th year players, not redshirt freshmen. Same for the backs and receivers - without guys like Spielman, Lindsey, and Washington sticking around we're playing a roster in year 3 that looks like a roster in year 1. Maybe we'll be better for it in the long run.
But for me, this is a case of the increased knowledge of the scheme/culture/whatever just not outweighing replacing guys like Morgan, Spielman, Ozigbo, and heck Tanner Farmer with redshirt and true freshmen the past 2 years. The jucos that were supposed to fill in didn't, and individual guys who could have been difference makers. I really believe this offense is light years different with a couple different player choices. If Washington figured his stuff out, our RB situation is way different. OR, if the staff decides he's not worth the risk and we sign somebody else, our RB situation is different. Same with OL - if Bland got here, or if we decided not to risk that and signed another guy, there's another more developed lineman available. Hindsight is 20/20 and all that though.
