Eddie Lacy (vs CHI, 6th for RB) and DeMarco Murray (vs MIN, 3rd for RB) join the top tiers this week. Both have nice match ups and should get high touch counts.
The only name that surprises me in tier 3 is Chris Johnson. He does have a nice match up against STL (5th for RB), but he's still only averaging 3.2 YPC on the year (which includes his garbage time 66 yard run in week 7).
Tier 5 is populated with second string running backs and primary backs with tough match ups this week: Steven Jackson (vs CAR, 22nd for RB), DeAngelo Williams (vs ATL, 17th for RB), Lamar Miller (vs CIN, 27th for RB), Pierre Thomas (vs NYJ, 29th for RB), Darren Sproles (vs NYJ, 29th for RB), Mike James (vs SEA, 26th for RB), BenJarvus Green-Ellis (behind Giovani Bernard), and Bilal Powell (vs NO, 15th for RB).
