Da'Rel Scott needs more than speed

As I continue breaking down film and updating prospect evaluations three players have jumped out for reasons both good and bad over the last couple of days.

Maryland RB Da'Rel Scott

Scott's 4.40-second 40-yard dash (some scouts had him in the mid 4.3s) sent me back to the tape and his acceleration and top-end speed are certainly evident there. He also shows soft hands and runs good routes out of the backfield.

However, Scott (5-foot-11, 211 pounds) is a narrow-based, upright runner who appears hesitant and does not have great lateral agility at the line of scrimmage. He is a bit of an entry-point runner, meaning he needs the hole to be open if he is going to make yards, and he lacks finishing power. Scott also needs to show more aggressiveness in pass protection, and even with his speed Scott's limitations make him no better than a mid-to-late round prospect.

Ohio State CB Chimdi Chekwa

Chekwa also ran a fast 40 time (4.38) at the combine, and on film he shows good instincts and a high football IQ. He also has size (5-11¾, 191) and is effective when he gets his hands on receivers in press coverage.

Chekwa is tight in the hips, though, and he often gets off-balance and takes time to recover when transitioning out of his backpedal or bailing in zone coverage. His closing burst is solid but he can be a liability changing directions in space, he lacks elite ball skills and needs to shore up his tackling. He's on the fringe of Day 2 despite his combination of size and speed.

Florida S Ahmad Black

Black's film and measurables don't quite match up. At 5-9.5 and 184 pounds he is undersized for a safety and his 4.7 speed in the 40 limits his ability as a cornerback. Being size and speed deficient are not good things for a defensive back, yet he is always in position to make plays on film and isn't afraid to lay his body on the line.

Black is a solid overall tackler who takes good angles and wraps up well in space, and while he is limited in coverage because of his lack of burst Black has good ball skills and maintains good position in zone. He will allow some separation at times and will struggle to recover but he is the kind of player who will work his way onto a team in the middle rounds and improve the back end of the roster as a solid reserve and special teams contributor.
