Representatives from 28 NFL teams, including assistant coaches from the New York Jets, Philadelphia Eagles and Pittsburgh Steelers, attended Nebraska's pro day on Thursday.
Nine Nebraska players, plus another prospect from Nebraska-Kearney, worked out indoors on FieldTurf.
Outside linebacker Randy Gregory (6-foot-4 5/8, 238 pounds) ran the 60-yard shuttle in 11.81 seconds and did the three-cone drill in 6.79 seconds. Gregory stood on the rest of his numbers from the combine in order to concentrate on his rigorous positional workout, during which he put on a show. Gregory is very lean and has narrow shoulders. He is extremely athletic.
Running back Ameer Abdullah (5-8 3/4, 202) ran the 40-yard dash in 4.54 and 4.53 seconds. He stood on the rest of his numbers from the combine, where he was a top performer among running backs in the vertical jump, broad jump, three-cone drill, 20-yard short shuttle and 60-yard shuttle. Abdullah did a really good job in the positional drills. He was really quick and caught the ball extremely well out of the backfield.
Wide receiver Kenny Bell (6-1, 196) ran the 40 in 4.38 and 4.37 seconds. He stood on the rest of his numbers from the combine, where he was a top performer among wide receivers in the vertical jump, broad jump and three-cone drill. Bell looked really good in the pass-catching drills.
Linebacker Trevor Roach (6-2 1/8, 237) ran the 40 in 4.78 and 4.79 seconds. He had a short shuttle time of 4.23 seconds and a three-cone time of 6.80 seconds. He had a 35 1/2-inch vertical jump and a 10-foot broad jump. He performed 25 reps of 225 pounds on the bench press. Roach is a priority free-agent possibility after the 2015 NFL Draft.
Nebraska-Kearney center Cole Manhart (6-4 3/8, 298) ran the 40 in 5.35 and 5.40 seconds. He performed 24 strength lifts. Manhart is a rookie free-agent possibility for a team.
