People that I know that have had conversations with him in the past, not friends of his per se, but people that have met him. I live in NC so I run into people. Some have come away with, he's a dumb jock vibe, others found him very intelligent. They all loved his personality, a little bit of a Gronkowski goofball in him, very easy going. As we know Gronk was very football smart.
My prediction on these QB's careers:
Drake Maye-Top 5 QB, All pro level starter for next decade, Will be better than Stroud, will get a second contract
Caleb Wiliams-Will disappoint like Trevor Lawrence, will be good but not reach great but gets a second contract as just good enough
JJ McCarthy-Will be a successful starting NFL QB. With a good team around him will put up good numbers, won't carry a team but won't be a QB you can't win with. In right situation could be Phil Simms type career. Very important he lands in good spot.
Jayden Daniels-Will be around the 15-20th best QB most years, will be the best rookie QB, but his lack of arm strength and middle of the field avoidance will keep him just above Justin Fields level for his career. He'll get a 2nd contract IF the team is not in position to get franchise QB elsewhere. Will not be a true franchise QB but will come tantalizingly close, and expect a really good first year.
Bo Nix-Busts out of league, never gets a second contract
Michael Penix-Likely long-term backup, can have a Matt Cassel type career if healthy but will never become a consistent NFL starter
Spencer Rattler-If he's really fixed his attitude problem from Oklahoma will have a Gardner Minshew type career, otherwise out of the league before 2nd contract
Michael Pratt-Has a chance to start in year 2 but most likely is a career backup with spot starts.
Jordan Travis-If recovered from injury (physically and mentally) will surprise, will have a long NFL career and if in right situation could be a long-term starter, most likely will be a #2 QB with spot starts for the next decade. If he is not 100% from injury then will be out of league in 2 years.
Just my opinion from looking at all the data/film. At least it's out there and in a few years we can all see how bad I am at this!!
Unfortunately, can't judge character, drive, determination, work ethic and how they react once they get a big contract. I also don't know what type of recall these guys have and how quick their brain processes. That's what made Tom Brady, Tom Brady.
