I’d equate that more to short bursts for the other guys. They showed IMO they could do it. They just didn’t get a lot of opportunities to do it consistently. All three combined had a third as many attempts as Montgomery.While I fall somewhere in between you and the national media, it still needs to be stated - YPC for the rest of the team wasn't good compared to what DM did. That's a fact.
I'm hoping Hall supplants the RB position a few games in and takes over. The others can get spot carries as situational backs. The OL definitely needs to make bigger strides this season or the running game may look bleak. The fact that Purdy can run should help open up some lanes though.
