92.3 had Greg Cosell on about a week ago and he was comparing/contrasting the QB's and he said the biggest "knock" on Mayfield is the height...and if that's all you can really hold against him, it's a pretty flimsy argument.
There's been a lot said about QB's under 'X height" not being successful in the NFL. Part of the reason for this is because there is a small(er) sample size because many GM's have a prototype built in there head so these shorter guys never get a chance. It's not like Mayfield's Doug Flutie short.
Keep in mind, this is coming from an advocate (me) of the big, strong arm QB type.
As long as the QB is accurate and can move the pocket with his feet/find throwing lanes, I'm fine with him.
Mayfield has, unfortunately, gotten lumped in with JFF because of his height, his mobility and his previous attitude. Mayfield's a bit different in that he's a worker, where JFF thought it would just come naturally and he could slide by. Mayfield has had attitude issues but he's not an addict, like JFF. To me, there's a lot to like about him and if they can have him sit & learn the same system behind Taylor, I think he could do well.
