Im not sure why people are so down on Grant based on his numbers in 3 road games against playoff teams. Here are how some other RB's did on the road against the Eagles, Falcons and Bears(only including the teams leading rusher):
Eagles
Jackson,B - 18 carries, 63 yards, 3.5 ypc
Torain,R - 18/70, 3.9 ypc
Turner,M - 15/45, 3.0 ypc
Brown,D - 15/50, 3.3 ypc
Bradshaw,A - 12/29, 2.4 ypc
Foster,A - 22/83, 3.8 ypc
Peterson,A - 22/118, 5.4 ypc
Jones,F - 11/81 yards, 7.4 ypc(week 17 against backups)
Starks,J - 23 carries, 123 yards, 5.3 ypc(Starks rushed for more yards than any other player in Philadelphia)

Thomas,P - 19/63 3.3 ypc
Stewart,J 13/31 2.4 ypc
Starks, J - 25/66 2.6(Obviously not a great game, but Starks spent the 2nd half running the clock against a team that did pretty well at home against the run.)
Bears
Best,J - 14 carries, 24 yards, 1.4 ypc
Jackson,B - 7/12 1.8 ypc
Lynch,M - 17/44 2.6 ypc

Funny thing is the Packers played the same three teams on the road this season and Jackson was their leading rusher in each game. Here are both RB's totals in the 3 games.
Jackson - 35 carries, 101 yards, 2.9 ypc
Starks - 70 carries, 263 yards, 3.8 ypc
Starks and Adrian Peterson both had road games aginst the Eagles and Bears, here are their totals:
