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

Jefferson was a robot and poor processor. If you look at Burrows strengths, it’s his ability to improvise, deliver the ball at different angles including on the run. And above all he has total control of what he is doing.

Harris was just the opposite of Jefferson. He was untamed & wild, but not unlike Jefferson. Nothing he did from a mechanics perspective was repeatable. I don’t think either would have been much better.
