They have to start recruiting for guys with more raw talent and building them from there. There will be busts, Wimbush. There will be successes, Kizer. But it's pretty silly to act like Tommy is properly discerning (over the phone and with virtual meetings no less) the mental aptitude of every top QB in the country with the expectation that he'll find the next Joe Montana or Tom Brady. It's a lot easier to look at the big guys with the big arms (or any recruit with an elite-ish tangible trait for that matter), recruit 5-6 every 4 years and coach them up. One is realistic and one is of fairy tales.
We're recruiting to a profile that just doesn't exist much in the NFL. How many QB's go in the top 2-3 rds of the draft every year 6'2 or under and/or don't have an elite physical trait to them? We just had an entire depth chart of them. The NFL isn't drafting smart QB's. They are drafting talented QB's. Who may or may not be smart.
Clark Lea did an interview with 247 sports last offseason and he was asked about length at the LB position and it's relevance to recruiting. He basically said, that they will recruit a 6' LB if they think he can play but they will not recruit a room full of 6' LB's because it limits the upside of the room. Time for Tommy and company to do the same. Have to start pushing the room into a physical profile that has more upside. You can do that with size, athleticism, arm strength, etc. but it needs to be done. If you cannot develop those guys then you shouldn't have a job.
