Both the safeties have had nice NFL careers, both the corners would have if they hadn't blown out their knees.
Mel Renfro gets the old-school nod, Cliff Harris for "if he could have stayed off the weed" honorable mention.
Ifo was that motherfukker, dude shut star WRs down, he should be starting in the league, but I'm sure he will eventually
Ward a Pro Bowler, Byrd a Pro Bowler, Ifo was arguably the best corner in the nation before his knee injury, and then you have Chung starting for the Super Bowl champs.
If you limit this question to guys in the league right now, Oregon has one of the best squads out there, which is crazy considering their (partly undeserved) rep on D in recent years.
