Good assessment, and likely true. Image though, if Brady moves it's like a big domino effect. I don't know if the Bengals would do it, but I'd consider sitting Burrow, for at least a half season, letting Daulton start. I know people hate that but I just don't see Burrow just taking the reins and running. There is so much of a difference between the NFL and college. He's going from a transcendent college football team to a team with a lot of holes. I believe Daulton has a year left on his contract.
I'm not sure any of the rooks are long term solutions other than Burrow. Herbert has a big arm, but I was less than impressed with him this season. I could see Mariota in San Diego.
