I don't believe we need a bruiser who's past his prime when we're currently featuring a much younger bruiser in Greene. McKnight also impressed tonight after a strong camp. Rushed for 32 yards off 7 carries to go a long with 3 receptions for 34 yards. Joe seems to be a talented backup who can push Greene for the starting position. Get McKnight into the open field and it'll be all positive yardage from there.
