I think Barrett does his best at whatever he attempts. So the answer is "everywhere." The question should have been, "at what position do you think Barrett Jones has played best?"
“ The Crimson Tide of Alabama” Now that has a majestic ring to it!
I mean, he was a Freshman All-American at RG, an Outland winner and first-team All-American at LT, and a Rimington Trophy winner and first-team All-American at C.
The resume says that he can play all of the OL positions at the highest level in college. I lean towards G or C being his ideal professional position because I don't know if he's the athletic freak that most NFL tackles seem to be.
Given his GPA and other achievements, I'd say the classroom and with his fellow man!
