Historically great.
He’s a giant Steve young.
No, he's not. He's not even close to what Steve Young was coming out of BYU. Steve Young played for Lavel Edwards and a guy named Norm Chow. They didn't run an RPO HS Offense. They ran more of a 5 and 7 step drop back vertical passing game with emphasis on the "8 zones" aspects of the field. Now, you can look up the 8 zones if you wish, that's something that Chow believed in, which came from his years at BYU and Utah I believe but it doesn't really matter. Basically, rollouts to buy time but not really RPO. More WC concepts. The bottom line is that Steve Young learned how to read defenses and was very good at it. He knew how to run a Pro Style drop back passing Offense. Fields, he's not that guy.
Fields, to me, is more Cam Newton then Steve Young. I don't question his athletic ability, at all. I just watch him play and I see a two read QB. He's not a guy who can drop back and survey the field and get to his 3rd or 4th or 5th read consistently. Some will say that this is a product of the Offense and that's fine, maybe it is, but still, I don't see it in his game and I am not spending a high pick on a guy who has never shown the ability to actually run a Pro Style Offense. This guy is not Steve Young, he won't audible out into different sets, read the defense and call a play from the line that gets you 6, he's not that guy. Steve Young, out of BYU, was that guy. He just got that crap kicked out of him in Tampa and so it wasn't till years later that you were able to see it.
