I mean, you can have that discussion now if you want, but imo, it's premature. Let's see what Rizzi does the rest of the season before crowning or clowning him.
Fwiw, I love his energy and barking at officials and holding everyone accountable for their performance on the field. That all was sorely lacking from Allen.
For the love of all that matters, please hire a HC willing to do these things, whether it's Rizzi or someone else.
