I want to agree with you.
But, I see MJ meeting with EC and saying "this is what I want our defense to be. Can you make that happen?" It's not like EC doesn't have the capability to stop different situations or put in certain players in certain situations. He has a 5-3. 3-4, 4-4, Nickel, whatever, in the the playbook. But EC and MJ need to be on the same page about how they approach and opponent. "Bend but don't break" or "GATA"? We're about to see...
The UCF vs. Auburn bowl game showed Chin can get after it. Does MJ let him off the leash?
If EC says yes, then keep him on. If he says "no, that's not what I do" then see ya!
