I'm still waiting for someone to refute me with some actual numbers on this.
The following projections I made for Powell are exactly equal to Donald Brown's performance so far this season:
48, 45, 101, 92 combined rushing/receiving yards each of those weeks (that's what Donald Brown has achieved).
That's 286 total rushing/receiving yards across 4 weeks.
That averages out to 71.5 combined rushing/receiving yards each week.
So that could be 50 rushing yards and 21.5 receiving yards.
Or 40 rushing yards and 31.5 receiving yards.
I'm really failing to see how that's an unachievable number
