No, this isn't me being an optimistic fan of this regime.
It's reality. Our O line and RB play has sucked. That's why we have been seemed to be a passing team (not really) and heavy on QB runs (which are heavily weighted by scrambles and sacks. That's where this discussion started, right? You want an offense that isn't relying so much on QB runs and instead, on RB runs. Well...so does everyone else, including the coaching staff. But, when that's not working, you have to try to produce offense somewhere else, and that's what they did.
Hopefully, that changes with improvement in those two areas. It's logical to think that our RBs will be more of the offensive production, if we improve the run blocking and RB coaching. Is that me being optimistic? No, because I have no idea if those two areas will improve next year or not yet.
