It took Dabo Swinney about eight years to build a juggernaut and he started out with a winning crew. HCDB is in year four and had bare cupboards when he arrived.
Any coach will tell you that games are won in the trenches. HCDB is building that but it will take a few more years for the trenches to be automatic. Most freshman O-linemen are not ready for D1 football. To play at the top level you need at least the two deep O-line to Brady to go at a moment's notice. We do not have that and because we are not in an automatic reload situation, it takes much more time. Heckel is out, players shifted, the reserves are not ready to take over, the O-line is not a strength.
And none of this excuses the way the D played today. The offense did not allow 63 points. Missed tackles alone could have changed the outcome. As could missed assignments.
The system works. I agree we need more middle of the field production, but the system works.
As to the need for a dual threat QB, TD needs to use his speed. Most QBs considered to be dual threat suffer with accuracy issues. The system is designed to exploit accuracy. However, when there is no O-line protection, no one has the requisite accuracy.
