DMC showed me that last year that he can play well on 15-17 carries. He needs a little warmup, but can still produce nicely on a limited amount of carries. He also performed well on 25+ carries, but given his injury history, I would be against it. I really don't understand the negativity towards DMC after last season. The only RB's that were running better from a statistical standpoint were Rawls out of SEA and AP when DMC started the last 10 games of the year. I can understand being hesitant about his injury history, but producing while being healthy is a different issue. And he's a far better receiver out of the backfield than Rawls and AP...and a better blitz pickup (although not great, but AP is really poor at blitz pickups).
My main question with Morris is if he can play the #2 spot and get in 8-12 carries. Then we can get 3-5 to Dunbar. That's why I liked Turbin so much. He didn't need a warmup to get going. He was never going to be a great back that you could start. But, you could get 4.5 ypc out of him in 8-10 carries and he could run on short yardage. I will say that I didn't like Turbin much in the passing game. His blocking was horrendous at times and he was limited catching passes.
If Morris can get back healthy and still has juice left in those legs and he can work fine with 8-12 carries a game, then I think we have a nice upgrade from Turbin because Morris can start and be extremely productive as a starter if DMC goes down and he's much better in blitz pickup. The one thing I always noticed about Morris is that he looked like the type of RB that defenses didn't like having to tackle. I'd like to see him healthy and for the team to use that to their advantage.
