To me, working with Jayden Daniels was like being asked to design and mold a solid gold ashtray. No matter what shape you come up with you're still going to have a big hunk of gold that gets the job done. It's not like he had taken some 'Ian Book-type' player and turned him into a playoff contending QB.
This is the same 'who made who' argument that many folks had in regard to Brees and Payton. No doubt Sean's move to Denver and his early success with Nix is helping to answer that question. When Kingsbury can 'convert' some journeyman player into a franchise signal caller, then he can officially be called the next 'Quarterback Whisperer'.
