Nick John and Don wouldn’t have thrown for….checks TD stats and yards
Like it or not will rogers is in the top 5 in every positive category for a qb except rushing
I'm not a Rogers hater, I think he was good for Leach's system and that a lack of a real deep threat outside receiver was a bigger part of his struggles than his arm strength, but he has tons of attempts/completions/yards that are essentially just extended handoffs. You have swing passes, screens, shovel passes, etc. in every offense to one extent or another, but Leach's air raid still makes it hard to compare QBs using stats.
Madkin and Wyatt are about as far back as I can offer an opinion on, but I would go with Fitzgerald out of the rest. So much is dependent on coaching, system, and surrounding talent though. I think if Fitzgerald had had another year of Mullen, he could have looked like a faster version of Chris Relf when Relf played Michigan in the Gator bowl. That would be pretty close to Dak his Jr year if not his senior year.
If you give me an offense that doesn't rely on a QB run and tell me to draft a QB from that list, I think I might take Tyler Russel (again, out of the modern ones; not sure about the older ones). I'm not sure Madkin ever got great QB coaching. I think as a Freshman he was probably close to early Jr. season Chris Relf, but didn't seem to continue improving to the exent Relf did. And of course we'll never know if Fant or Conner could have been anything because of lack of supporting talent and/or coaching.
