The split between Bills RBs Fred Jackson and C.J. Spiller has stayed nearly the same the past three weeks.
Jackson's production, however, has far exceeded that of Spiller. Is the offensive line partly to blame for that? Sure, but it's the same group of blockers for each back.
The true variables are Spiller's running style and the plays the Bills call for him. More often than not, it doesn't work out.
Jackson got 46 snaps to Spiller's 25 in Week 5. Spiller has 18 more carries to Jackson but only has 12 more yards to show for it (Jackson' 43-202 vs. Spiller's 61-214). Jackson has seen more work in the passing game with 26 catches for 228 yards on 33 targets while Spiller has 13 catches for 106 yards on 14 targets. Both backs have a receiving TD. Jackson suffered a bit of an ankle injury but said he was OK after Week 5's game, however it's something to keep an eye on.
