Even that doesn't matter to me as much as what the space he creates in the pocket by being able to proactively attack pass rushers. In zone protections, when he doesn't have anyone to block, he can come over and help another OL out much more effectively, creating enough space to keep the quarterback from getting spooked, and he's got the athleticism that if he reacts late he can still be effective. In the run game, he can get out to cut-off blocks that other guys can't, and on screens he could pull way out and clear a lot of room.
