Exactly this.If Caplan hadn't sent out his Tweet earlier today I'd be more concerned about this from an Ajayi perspective. But Caplan is really dialed into the Eagles. I think it's a near mortal lock the info he got came from the coaching staff.
ETA - Blount starting this week with Ajayi having a minor role and then coming out in Week 11 as the starter after the bye does make a ton of sense as I said earlier.
I could see a 15/5 Blount/Ajayi split this week, then the bye, then something closer to 18/8 for Ajayi going forward.
