Darelle Revis, Hands down a rookie who walks in and starts from day one, and played phenomenally against some of the leagues top recievers. Would be the DROY if David Harris didn't decide to take it from him. Also would be leading the team in tackles if Harris didn't get the chance to start...
David Harris...the guy is a beast...and he also pressures the quarterback when he is told to rush...makes solid tackles, good in coverage and a quality pass rusher....2nd round pick, looking like a steal
Revis. Shutting down T.O. and Moss, amongst others, in his rookie season shows he is the real deal. Harris is a close second.
Personally my pick would be Rhodes, but you can make strong arguments for Cotchery, Harris, Revis, Mangold and Washington.
David Harris... The run-defense seemed to step it up and began improving once he started playing. He made a big difference and should continue to make a big difference in the middle for a while.
