Nmandi Asomugha and Rob Ryan
In Rayn's defense Nmandi is stellar. He is the best press CB in the league and can match up one on one and handle any reciever in the league.
The Eagles were idiots, they put him in the slot and forced him to play off the recievers and zone too much. As for last year, I think he knew that team was doomed, just like everyone else did.
In Oakland, they assigned him to the biggest baddest reciever and let him go after the guy. His ability to disrupt a reciever's route at the line of scrimmage is unmatched. He shuts down any inside routes with his physical play and pinches recievers into the sideline if they try to over top.
