It was run blocking that separated the Smith and Free. Smith was a positive 9.something and Free was even stephen. Livings did well in the running game. Passing game... not so much. I look at Cook's ratings and I shake my head a little because he didn't seem to be that good. Bern really was a car wreck at guard for most of the season, especially vs the pass. The funny thing (not funny "ha-ha") is that both Livings and Bern were worse vs the pass than they were the run.
