So Revis isn't in the top 5 even? I think Ivory should be around 3-5. Ridley is back now, so we have a solid backup RB. That, and RB is one of the most replaceable positions in the league.
No, Revis isn't even close to top 5. We've maintained good defenses without Revis these past couple years and we have better depth at the CB position. Ridley didn't play at all and he is not a "solid back up". He's a mediocre runner and he can't do what Ivory does. Our run blocking sucks. Ivory just happens to be a machine. We win every game Ivory plays well in and lose if he's banged up or out. Revis is a luxury.
