Last year was Jerry's first as a full time starter, with a rookie next to him, in a new zone blocking system, and he was a bit below average.
He ranked #18 overall of all NFL RG's, #12 in pass protect (2 sacks, 3 hits, and 15 hurries), and #23 in run blocking. He also got a good grade on one screen pass.
Jerry had three games below average, one game above average, and 12 average games. He was consistently average, not bad. I expect him to develop and adapt this season to become at least above average, and maybe better than that.
