Lawson is more prepared coming out of high school than Clowney. He's much more polished at his position than Clowney was. With that said, Clowney's ceiling is and has always been much higher.
In all fairness, how polished can a High School player really be? I'd much rather a raw specimen than someone who's already plateaued on what he can do technically.
Not knocking Lawson either, but I think the reason he's getting so much attention is mostly due to his raw potential, rather than his grasping of football fundamentals.
With that said, I've only watched highlight of Lawson, so I'm certainly no expert. I just know I want him because every other big school wants him.
