I watched most of the game and I noticed the same thing I noticed while he was at UT. He has unique athletic ability/speed for a guy his size and has soft hands, but he is the weakest blocker I've ever seen for someone 260. I mean charmin soft, almost like he doesn't want to hit anyone.
I disagree that he won't get a look in the NFL though. The fullback position is basically extinct in the pro game now, with the number of formations and the popularity of the passing game, so it's not like you have to be a good blocker. He's big and he can catch the ball and run, so I wouldn't be surprised if he made a practice squad. I think the biggest thing that would hold him back is his work ethic.
