Interestingly enough, if there is a weakness in his game, it is his pass protection. I actually have my Georgia Bulldogs t-shirt on right now (gag gift from my in-laws), so I feel I can talk freely about him.
He is an excellent run blocker from what I have seen, but struggled when the Bulldogs had to go one dimensional and play from behind, passing the football on every down. I am talking specifically about Boise and LSU. He allowed way too much pressure against Boise in particular.
I personally think he will be good at the NFL level on a run first team like the Ravens or Jags, but would end up being just an average player in a pass first team like Dallas. Having said that, "average" would be an upgrade compared to 2011. so it depends on what you are looking for.
Just my opinion.
Oh, I would expect him to get picked up anywhere from late second to mid-third when all is said and done.
