This.
Just as Mullen came in during his first year and leveraged what little strengths we had into a competitive team... I think this year proved that we don't have the personnel to run a pass-heavy spread offense. This is going to be very, very unpopular, but I want Dak Prescott to start next year.
And for the record, I think Tyler is the best QB that we've ever had on campus. Tyler, in the right offense (like Bama's), could be the best QB in the nation. But his style just doesn't fit the other pieces we have on offense right now. We're more set up for a run-heavy option like what Tebow ran.
It's all about using what personnel you have to make your team better... and I think we'd be a better team with a running QB who can pass.
Edited to say: When I say that this year proved that we don't have the personnel to run a pass-heavy spread... I say that because we didn't really move the ball versus any team that had a pulse on defense. If we dropped 30 points against Bama, aTm, LSU, or OM, this statement would be invalid. But I think everyone can agree that when we played teams who had a clue on defense, we struggled mightly on offense.
