anywhere between crap and ok for the OL. Even his senior year he comes back and has to run with bad OC, bad QB play, and 3 starting OL were out by about game 4 and they were starting a 260 lb freshman RM at RT. Bad OL and no support and he still had an awesome season.
But overall I just don't like to dabble in some stats when they depend so heavily on other factors. We can get something from them, but they definitely don't tell us everything about the situation. When it's so specific to one play itself, and as specific as 3rd down running, there are so many other factors that can lead to the success of that play.
