I don't thinkMD was playing many snaps on what would be considered "running downs" though his snap count seemed to have been increasing with each passing game, so he was playing more run fits than to start the season. AO is still the starting DE on that side though and it's because he's the best run defender option we have opposite Cam. Once MD's game has totally rounded out, he'll take over as the starter/full time player like Cam is on the other side.
