Disruption not him personally. Disruption to reduced play for DS and Cook. Won’t keep that many RB’s and Moss probably is the odd man out. May go another way, but guys who have been playing together for some time, won’t be.
May be a disruption in the locker room, may not be.
I get it. So that answers the main question, why doesn’t DS get the bulk of the work. They must not believe in him.
That being said, don’t believe he has had a great line in front of him. The play calling is pass heavy - set up the run with the pass. I don’t think he’s a bad RB, hadn’t gotten the greatest of chances.
