It's just his opinion. I don't read the guy often, but if he didn't add a little "sauce" to his opinion pieces, they would not be read.
I love how many experts there are on QB mechanics. I think he was in the Heisman "team photo" 3 times. His team, for the most part, dominated offensively against superior competition and under his direction. We're I his coach, I'd be more afraid to screw him up than to prepare him for "Combine Experts". What did he do???? That should be the primary driver for our picks. Not how. Otherwise, you end up with Maybins and Flowers.
