Positive: Big cornerback who's displayed the ability to shut down opponents throughout his college career. Jams opponents at the line of scrimmage, aggressive throughout the route, and fights hard to defend passes. Loses nothing transitioning to run with opponents, shows a terrific burst out of his plant, and has opponents throwing away from him. Can stay on the receivers' hip out of their breaks and plays with a explosiveness.
Negative: Must improve the consistency of his backpedal. Seems to get lost in zone coverage.
Analysis: Walls displayed the underlying skills to be a top cornerback prospect throughout his college career. He must fine-tune the details of his game, but he is a prospect who could see significant action in nickel packages as a rookie in the NFL."
Strengths: Ideal physical specimen with NFL tools. Good size and physique with long arms. Good athlete with speed, quickness and loose hips. Prefers to play press coverage and can stick tight with most receivers. Finds the ball and breaks up passes. Improving as a tackler. Plays on special teams.
Weaknesses: Inconsistent both in coverage and versus the run. Erratic tackler. Gambles in coverage and will give up completions when going for the ball. Doesn't get many interceptions. Has had some off-field issues, though nothing major.
Projection: Really took his game up a notch in 2010 and should be a late-round pick, though still not the player he should be. If he can harness his skills he has a chance to be a major contributor a few years down the road."
