BIO: Senior totals included defensive numbers of 33/2/4 with an average of 10.8 yards on 24 punt returns. Junior totals included 36/1/7 on defense with an average of 9.6 yards on 40 punt returns and 27.7 yards on 19 kick returns with one score.
POSITIVES: Versatile cornerback with added value on special teams. Reads the action, makes good decisions and works well with the safety. Tracks the deep ball, possesses a good break on the throw and works to get a hand in. Defends the run and mixes it up. Elusive when the ball's in his hands and impacts the game returning punts or kicks.
NEGATIVES: Lacks the top footwork, body control as well as recovery speed. Does not show a lot of explosiveness to his game and slow getting off blocks.
ANALYSIS: While a solid corner, Duff has not been an exceptional defensive back or one that's made a lot of plays. May be best facing the quarterback though his greatest worth to an NFL team could be as a return specialist.
