Representatives from all 32 teams -- including New York Jets general manager Mike Maccagnan, Seattle Seahawks general manager John Schneider and Tampa Bay Buccaneers general manager Jason Licht -- were present for Oregon State's pro day on Friday.
There were 20 players from Oregon State, one from Western Oregon and another from Southern Oregon who worked out indoors on FieldTurf.
Quarterback Sean Mannion (6-foot-5 3/8, 233 pounds) had a lights-out pro-day workout, throwing the ball like you'd expect from an NFL quarterback. A lot of teams are likely to take a more in-depth look at Mannion in the weeks leading up to the 2015 NFL Draft.
Defensive end Obum Gwacham (6-5 1/4, 249) worked out as both a linebacker and defensive end. His best position in the NFL, however, is probably going to be as a pass-rushing defensive end with his hand in the ground. Gwacham stood on his numbers from the NFL Scouting Combine, where he was a top performer among defensive linemen in the 40-yard dash and broad jump.
Cornerback Steven Nelson (5-10 3/8, 196) ran the 40-yard dash in 4.49 and 4.54 seconds, and then stood on the rest of his numbers from the combine, where he was a top performer among cornerbacks in the bench press. Nelson showed quickness in his pro-day workout, but he has a tendency to grab receivers while in coverage; he was called three times in the Senior Bowl for illegal contact and once for holding. This is an aspect of his game he needs to improve on. Nelson could be selected as early as the fourth round of the draft.
Western Oregon wide receiver Tyrell Williams (6-3 1/2, 204) ran the 40 in 4.42 and 4.44 seconds. He had a 39 1/2-inch vertical jump and a 10-foot-7 broad jump. He did the 20-yard short shuttle in 4.11 seconds and the three-cone drill in 6.55 seconds. Williams is a potential free-agent pickup for a team following the draft.
