the snap counts at RB, WR, TE seem about right

At RB, Williams got 83% of the snaps (49 to 10) over Corum. I think over time that will end up more like 75/25. But it's not that out of line with what you'd expect.

At WR, Whittington is this team's WR3 and Atwell the WR4. Yet Whittington ended up with 30 snaps (partly because of when Nacua was out) to Atwell's 25. So again, I think right in the range/ratio we should expect.

And at TE, they divided snaps between Higbee (35), Parkinson (29) and Allen (22). For this game at least, Ferguson hasn't earned playing time yet. He missed a lot of camp so that doesn't seem surprising at all. He'll earn snaps as the season progresses.
