I think Joe Brady would be a very good HC here, however I don’t think he’d be all that interested.
By my estimation he has NFL HC aspirations & while being a college HC would only help bolster his resume, I don’t think coming to Miami would help him all that much, I mean if he turned us around it would definitely make him a top HC candidate around the league, but in all actuality he doesn’t need to risk it coming down to Miami, he’s already making himself a legit commodity due to his success with Joe Burrow & what he’s doing in fixing Sam Darnold.
If Carolina finishes above .500 this season he will no doubt be a hot name in the Coaching search market for teams, he’s pretty much already put himself in place to become a HC in the near future, coming to Miami would really only be a step back for him, unless he just really wanted to do it, but otherwise if you're his agent you would have to advise him to keep away from a trap job like Miami. All he has to do is stay a pretty good OC in the NFL for the next year or 2 & he’ll get a HC job in the league no problem.
