Where would you rank Tramon Williams, Stanford Routt, and Antonio Cromartie among cornerbacks.?

These guys are the best cornerbacks that are not the #1 CB on their team. And why not? Well, because they sit behind Darrelle Revis, Nnamdi Asomugha, and Charles Woodson on the depth chart. So where do they rank? Personally I rank Routt and Cromartie outside my top 10, maybe around my top 15 or 20 CB's because they aren't the most spectacular of corners and don't line up against the opposing team's number 1 WR. However the same cannot be said for Tramon Williams. Remember that pick six he had against the Falcons in the divisional round? That was when he was covering Roddy White. Because of Charles Woodson's age he can't always cover the young fast number 1 receivers, which is where Tramon Williams is able to step in and take on the faster guys. I rank Williams in the top 5-7. Sometimes memories of his incredible postseason play that involved 3 interceptions pushes me to rank him number 4 ahead of even Champ Bailey and Asante Samuel. Where do you rank each of these cornerbacks?
