I think Hurst, the kid from S Carolina, and maybe even the Tennessee LT (Richardson, I believe) are better.
Nix is a very good player. But, against Alabama in the biggest game of his career, he was pedestrian at best. He did get injured but that wasn't until the third quarter. In the first half, against NFL caliber linemen, he was not dominant. Not by a long shot. Sure it is just one game. But, man that was a big one.
