The use/performance of RBs in the three pre-season games so far doesn't provide much in the way of clues about who gets the most rushing yards this season; just raises a couple more questions for me, really.
Foster and Lewis are the only RBs to get carries in all three contests, and both did about the same, if you subtract their longest run for each game before calculating their YPA. Both fought hard for the extra yard after contact. Lewis seemed to be a bit more successful at that.
Bolden got carries in the first two games, and had a pretty solid "adjusted YPA" - only got stuffed once, IIRC.
The only carries for Daniels came in the first game, and he actually ran with a bit of authority. I'd like him on the PS/scout team.
Burkhead only got carries in the second game, but may have gotten some in the 3rd game, if he'd been healthy (something to consider for the future). He got stuffed a couple times (once was a horrible blocking breakdown), but fought hard for yardage.
Gillislee finally got healthy enough to get carries in game-3 (his only appearance so far).
White appeared in all three games, IIRC, but only got carries in game-3. It was only four carries, but it's maybe interesting that he's the only RB who didn't get stuffed once. All of his carries went for decent yardage.
In contrast, Gillislee had the one really long run, one other carry for good yards, and the rest of the time averaged about 1.6 yards (even extracting his two short goal line carries). I'm not implying that this is necessarily a problem, just saying that he probably needs more work to get into rhythm with the offense. Most of his "truncated" carries seemed to result from the hole not being where he expected it to be and/or from running into the backs of his own blockers.
Anyway, it will be interesting to see who gets carries tonight against NYG. White and Burkhead are almost certain to NOT participate. Daniels and Bolden are almost certain to get a lot of work. Foster, too - and it'll be interesting to see whether or not he lines up in the slot at all.
Gillislee might get a few more "refresher" carries tonight.
I wouldn't expect to see Lewis at all. However, if he gets a lot of work, that might get folks speculating about his future roster status.
