How do you think every RB increases their YPC? By breaking one now and then. Discounting big plays is the opposite of how you should critique them, especially those that aren't just home run hitters and move the chains. He's done a very good job behind this line this year, especially for when Foles was playing and the o was a stationary target. If you wanted to say that he hasn't had enough big plays it would be a better argument than you're making now but to discount the OL play and simply look at his YPC is just silly.
He's obviously fast enough and has finally stopped making extra moves trying to find or waiting for holes that aren't there. He was drafted to do that but has now figured out he just needs to hit it more often and go from there because he's getting contact anyway. When he gets a hole, it's usually close to a 1st down. He averages 2.4 Yards after contact while needing to run sideways most of the year. The RBs ahead of him are already heading north though less congestion when getting that contact. Henry always is near the top of that list but how often does he get YAC if he hasn't yet gone vertical,.
