If he did say it exactly how you laid it out and someone in our organization knows it as a fact, then I agree, don't consider him. But it's utterly absurd to believe an 17 year old recruit that would have otherwise signed with us ultimately ends up not picking GT now because someone somewhere on the internet once said that a coach once said not nice things about GT years ago to some other recruit while in some other job. Utterly absurd.
And you realize that all OC's at some point had never called plays before, right? Having not been an OC before does not mean he is "in no way qualified to call plays as an OC". Otherwise no one would ever be qualified to call plays as an OC. Ever. He's highly respected in coaching circles and widely considered one of the best assistants in the country. Nick Saban essentially demoted once of his longest serving assistants to make space to hire Key. He don't garner that kind of respect by not understanding X's and O's.
