In a secondary with three potential first-round prospects, Bradley Roby is the standout. He is a gifted athlete, with terrific instincts and ball skills. And he's got the kind of speed that helps him close fast, pursue ballcarriers and run with the fastest receivers an offense can throw at him. Roby is likely to miss some time this season serving a yet-to-be determined suspension or some other punishment for an arrest following an alleged bar fight. Still, whatever time he's on the field will be spent disrupting plays; he has five interceptions and 23 pass breakups over the last two seasons.
