For what it's worth, since I've been sharing them out on Twitter, I figured I'd post the Pats RB snap counts here, too.
Snaps by quarter:
Dion Lewis: 15, 13, 7, 0
LeGarrette Blount: 0, 8, 10, 11
James White: 0, 0, 7, 8
Brandon Bolden: 0, 1, 0, 0
The big takeaway to me from that isn't Lewis vs. Blount. It's Lewis vs. White. Using PFF's snap count data, (which differ slightly from the ones I have above, but I have to work with what I have), James White played 1 snap in the first two weeks combined, and 17 snaps against Jacksonville. All of them came after Dion Lewis was done for the day.
So let's ignore the Blount/Lewis competition and just look at James White. What happens if we assume that James White actually seeing playing time was just New England's way of giving Dion Lewis the afternoon off, (which seems like a pretty safe assumption, to me)? If we add White's numbers to Lewis', Lewis would have finished the week as RB7 in PPR, right between Le'Veon Bell and Adrian Peterson. Even with Blount coming in and getting all of the touchdowns. So Blount isn't really hurting his value at all.
Another interesting takeaway? In a game where New England had a huge lead and was supposedly trying to pound the ball to salt it away, "Passing game RBs" (Lewis/White) accounted for 63% of all RB snaps, while "rushing RBs" (Blount/Bolden) accounted for just 37%.
The last takeaway for me is just the fact that New England gave Lewis the afternoon off at all. The only other offensive player they seemed to give a reduced workload compared to the first two games was Rob Gronkowski, (who played 98%, 94%, and 66% of New England's snaps, respectively, over their first three games). It's hardly dispositive, but when you and Gronk are the only guys New England is giving a break in the second half, it's certainly suggestive. I think the Patriots really like Lewis and wanted to preserve him for when they needed him later.
Add up everything, and the Jacksonville game was a huge positive indicator for me. New England never loved Ridley. That's why they let him walk. They let Jonas Gray walk. They let Vereen walk, too. They even let Blount walk, remember. We've got a lot of evidence that New England is okay rolling with those guys, but not exactly in love with them. Whereas I'm starting to get the vibe that Belichick and Co. really, really like Lewis. More than they ever liked those other guys, at any rate.
In PPR, I'd have no compunction against valuing Lewis as a low-end RB1 the rest of the way. (In standard, he's probably more of a mid-RB2.)
