Last of a five-part series

The NFL draft is more than seven months away, but Pro Football Weekly personnel analyst Nolan Nawrocki has already invested months of work in the player evaluation process. This year, PFW is proud to introduce the latest product in its line of pre-draft periodicals — the Draft Newsletter series. For $24.95, you will receive four Nawrocki-authored newsletters that are designed to keep you up-to-date on the latest happenings as they relate to the NFL draft — including the most-respected player reports and rankings available anywhere.

To give you a taste of what you will receive when you subscribe to this wildly popular new product, we are releasing some of the 222 scouting reports that appear in the first installment of the newsletter. We are counting down the top 15 senior prospects, so be sure to check back daily for the latest player reports.

The numbers in parentheses after each player indicate height, weight and 40-time — "E" means height, weight and speed are estimated or from an outside source; "e" means only the 40-yard-dash time is estimated or from an outside source.

3. RB C.J. Spiller, #28
(5-11, 195, 4.35 E) Clemson

A very sudden, cat-quick multi-purpose back who operates best in space, Spiller lacks the run strength to consistently pound the ball inside and has shown a tendency, especially earlier in his career, to bounce outside. Is not powerful but will rip through arm tackles and does not go down easy once he gains a head of steam, showing very good contact balance. Possesses the top-end burst to take the corner and can accelerate and pull away from defenders in the clear. Really emerged late in the season after then-interim and new head coach Dabo Swinney took over the play-calling and well distributed his touches. Catches the ball with ease and is exceptionally elusive after the catch. Brings a home-run threat to the return game. Has run track at Clemson, and it has hindered his development in football. Is not overly tough, does not like to be hit squarely and could always be at risk of popping hamstrings given his dynamic gear change and rare acceleration, but he possesses the physical traits to be a difference-maker in multiple phases and is a game-changer.

Projected round: 1

2. OT Trent Williams, #71
(6-4 1⁄2, 305, 5.15 E) Oklahoma

Thickly built, long-armed, quick-footed giant who is as adept run-blocking as he is pass-protecting. Has a strong anchor and can stop a charge. Plays with natural knee bend and balance, shows outstanding recovery quickness against speed and counters and is seldom on the ground. Can shuffle, slide and mirror. Is light on his feet, loose in the hips and easily can flip his hips and wall off defenders. Rolls off the ball low, gets into blocks quickly and drives defenders off the ball. Quick to the second level and can sustain downfield. Flashes a mean streak and shows the ability to dominate. However, he will play down to the competition, gets lazy at times, lets his pads rise and takes plays off. Needs to learn what it means to work and can become a more consistent overall finisher. Lined up on the right side opposite Vikings 2009 second-rounder Phil Loadholt as a junior and has played multiple positions on the line. But Williams is plenty athletic enough to handle the left side he will occupy as a senior and could play anywhere in the pros if he is willing to commit himself more to the game. A top-10 physical talent.

Projected round: 1

1. FS Taylor Mays, #2
(6-3, 236, 4.45e) USC

Rare physical specimen who stepped into the starting lineup on a national championship-caliber team from the time he was a freshman and made an impact. Possesses a muscular, rangy build with a very strong upper body, linebacker size and cornerback speed, combining for a very imposing presence. With rare measurables and an intimidating on-field presence, could possess more potential than any safety ever to come out of the Trojans' secondary, which features a long line of greats including Ronnie Lott, Dennis Smith, Mark Carrier and Troy Polamalu. Although Mays does not possess the cover skills and ballhawking, playmaking ability of Sean Taylor, he is the closest athletic specimen the NFL has seen come from the college ranks since Taylor. Could become a more reliable tackler, as he can be overaggressive seeking kill shots. Shows some rigidity in his pedal, but is quick to plant and drive on the ball and shows great closing speed and recovery quickness. Has a 40-inch-plus vertical jump and can take the ball out of the air. Can run the alley and deliver some slobber-knockers. Explosive, blow-up hitter (see Rose Bowl vs. Penn State). Studies the game and does extra work to improve. Should step into a starting lineup immediately and has the ability to change games. A tempo-setter with Pro Bowl potential, Mays is one of the most athletically gifted safeties to emerge from the college ranks in the last 20 years. Top-10 talent.
