re: How much better would Jordan JJefferson/Brandon Harris have been under Joe Brady?

Fair questions, actually.

There is a reason Oklahoma, Clemson, etc, rock out almost every year. There’s a reason Alabama had a string of consistent QB play, as well.

You commit to something in practice and then execute that. Les Miles, bless his heart, committed to power running and playing defense. That will win games but not championships, not anymore.

In this system, Jefferson and Harris would have been better. Great? No. Better? Yes.
