I agree with what Bradshaw has said recently, Surround the kid with playmakers and let him evolve.
It's exactly what SF has done whether it is Purdy or was Jimmy G, decent- B- arm and good enough mobility and playmakers all over, let Kenny read the D and make plays, Fields/Nix/Penix rather give KP the year work with Smith and a better OL.
I honestly think aside from JJ and Danials, these QBs will not live up to the hype. I don't think with the ego Caleb has he can reach Mahomes or at best Tua. He if drafted by the wrong org and if doesn't take the NFL Serious u will have another Kyler or Manziel, which the team that gets him wont tolerate for more than 2 years and then Caleb will be in a Mayfield situation
