Completely unsubstantiated rumor.
I doubt he was required to read defenses at all in college. I would expect a high degree of "busted plays" when you look at one read, or maybe two. Once he decides to move, every play is going to look like a fire drill, but how often was that because coverage was inadequate vs. his initial receiver was not open on first look? This kid, like virtually all college QBs, is going to have a big learning curve, and athleticism is only going to take him so far. His image polishing work recently aside, along with the scripted and carefully managed pro day, may end up fooling someone at the top of the draft, but he is far from a "can't miss" type you would want to spend a top draft choice on, IMO, which admittedly is not one of an expert. I just do not like him or his game.
