I've read a while back that the staff's intention is to utilize DMC's ability as a receiver on 3rd downs. It'll save Zeke from an excessive number of reps and afford DMC an opportunity to be productive. I'll be interested to see whether it's DMC or Morris getting running plays to spell Zeke as well. Seeing as how DMC has been elevated above Morris, I'd assume it'll be him doing that as well.
As I recall, Morris started the season being quite productive and then tailed off with lesser carries. He's also not especially productive in the passing game, so there's that also. As good as Zeke has been, it's difficult pulling him to assign touches to others. Here's hoping DMC finds some success and is significantly productive for our offense, whereas Dunbar has also been quite disappointing in his limited action.
