Read & React: Good anticipatory skills. Reads the action and breaks on the ball quickly. Can be beaten with good play-action fakes. Lacks the deep speed to recover and has to be protected over the top by a safety.
Man Coverage: Flashes an aggressive pop at the line of scrimmage when in man coverage. Good lateral agility to turn and run with receivers. More quick than fast, and can be beaten over the top if left alone in man coverage.
Zone Coverage: Alert and active defender when in zone. Reads the action quickly and gets a good break on the ball, especially on short and intermediate routes. Disciplined defender and reliable tackler.
Closing/Recovery: Lacks the straight-line speed needed to recover if beaten initially. Quick feet and possesses a very good first step to accelerate out of his breaks to close. Has good leaping ability, but lacks the height teams prefer and can be beaten by bigger, taller receivers. Natural hands and an obvious threat with the ball in his hands.
From CBS Sports:
Run Support: Aggressive fighting through blocks to come up in run support. Highly active defender and an effective open-field tackler.
Tackling: Secure open-field tackler who breaks down in space against shifty athletes. Not a big hitter, but wraps his arms around his target with good drive for a player his size. Struggles some against bigger receivers, but has good strength to drag them down quickly.
Intangibles: Knack for returning punts/kicks didn’t just develop in college — he set the record for Robinson High School in Tampa with seven returns for touchdowns as a senior. Good athletic bloodlines. Cousin, Gilbert Arenas, plays in the NBA for the Washington Wizards.
