I think Frost can be legitimately criticized for not recognizing Burrow's talent while Orgeron treated Burrow like a five star. Here is how much Orgeron thought of Joe and what he said to Joe:
"I can’t promise you the job. But, Joe, you’re going to be my starting quarterback.
I’ve watched you on tape. I heard you today. I’m totally confident you’re going to be our starting quarterback.
Look at me, Joe, I got to win here. I’m throwing it all on the line. You’re going to be our starting quarterback. I’m not guaranteeing it. You’re going to have to earn it. But if the head coach thinks you ought to be the starting quarterback, guess who is going to be the starting quarterback?"
