From NFL.com's Pete Prisco... http://www.sportsline.com/nfl/story/8050353/1 Defensive rookie of the year: Dunta Robinson, CB, Texans. This is the next great corner in this league. He should be on his way to the Pro Bowl as a rookie. That's how well he has played. Runners-up: Madieu Williams, S, Bengals; Jonathan Vilma, LB, Jets; D.J. Williams, L B, Denver Broncos; Erik Coleman, S, Jets.
