Really good article on Barner and what it takes going from college to the pros.
Perhaps the most stunning thing for Barner, besides the inevitable rookie wall, was how much more he was asked to do mentally at the NFL level. While his Oregon meetings with other backs were generally more toned as "Zone left? Zone right? Got it!", the Saturday night quizzes he and his battery mates had last season were far more comprehensive. Barner told me that the expectations regarding reading blitzes, understanding the positions of defenders, and wrapping your arms around the ways in which plays can change on the fly came as a fairly major surprise. If you want to know the 14 things you could or should possibly do when the weakside linebacker moves incrementally just so, taking a few of those quizzes is a good way to start -- and if you're not on the ball in those meetings, you won't get the ball when it's gametime.
"Oh, absolutely -- the rookie wall!," he recalled with a laugh. "For me, it was about Week 7. I was actually sitting in a meeting room, sitting next to DeAngelo, and I said, 'I don't know if I'm going to make it.' And DeAngelo yells out, 'He hit the rookie wall, y'all!' It's just a long season.
