Personally, I thought Grant played well today.
In fact, while watching the game, on more than one occasion, I said, "Man, Grant is playing much better"
Over 4 yards a carry is pretty decent against nearly any run defense. Against the Titans, it's very good.
Grant was not the reason for our loss. Sure, you could make the argument that if he had a spectacular game, we would have won. But you could make that argument about every player on the field.
If Rodgers played better, we would have won. If Woodson picked off a pass and returned it for a TD, we would have won. If Jennings only broke a few tackles and ran for a TD, we would have won. Etc. Etc.
