A possible first-round pick along with the brother of a perennial Pro Bowler, Emmanuel Ogbah and Glenn Gronkowski worked position drills only at their pro days.

Emmanuel Ogbah doesn't know when he's going in the 2016 NFL Draft, but the 2015 All-American is hoping that he's done enough to prove his worth as a high draft pick.

Ogbah and nine of his college teammates participated in Oklahoma State's 2016 pro day on Tuesday in Stillwater, Okla., in front of personnel from 30 NFL teams.

The 6-foot-4, 237 pounder stuck to his marks at the NFL Combine in which he ran the 40-yard dash in 4.63 seconds while recording the third best vertical and broad jump totals among defensive linemen.

Instead, Ogbah participated in positional drills.

"I'm pleased with my progress so far," Ogbah said via OKState.com. "There's a lot of stuff I can keep getting better at, so I'm just working on it and getting better every day."

Former Dallas Cowboys general manager and current NFL Media Analyst Gil Brandt said that those on hand "thought that he looked much better working out at defensive end than at linebacker."

Ogbah has been linked to the Redskins in various mock drafts over the last two months and it is easy to see why.

During his junior season in 2015, Ogbah earned co-Defensive Player of the Year honors for the Big 12 conference as he recorded 13 sacks including 7.5 in the first six games of the year.

"Just give me a chance to rush the quarterback. That's one of my favorite things to do, just rushing," Ogbah said at the NFL Combine. "It'd be a great thing for me if I could just do whatever I want just to rush the quarterback. I'd be glad to do that."

Also participating in Tuesday's pro day was cornerback Kevin Peterson, who participated in the Senior Bowl.

Peterson improved on his 40-yard dash time from the NFL Combine, going from 4.66 seconds to 4.50 seconds.

"I felt good," Peterson said. "It was my last time to get on this turf and actually perform. It was a lot of fun."

In 38 games for the Cowboys, Peterson totaled 103 tackles with 17 passes defensed and four interceptions.

'Baby Gronk' get his chance to shine

No other fullback is going to get as much attention as Glenn Gronkowski, the younger brother of New England Patriots All-Pro tight end Rob Gronkowski.

Gronkowsi, along with 11 other prospects, participated in Kansas State's pro day in Manhattan, Kan.

The 6-foot-2, 239 pounder opted to sit on his NFL Combine marks (4.71-second 40-yard dash, 17 bench press reps of 225 pounds) while participating in position drills.

Gronkowski is somewhat of a wild card entering the draft, as he's opening to playing several different positions including tight end.

"Obviously I didn't play it that much in college, but it's basically the same thing as fullback," Gronkowski said at the NFL Combine. "You're just on the line. Obviously, it's a different game completely, you don't have much time to react, stuff like that, but definitely say I can adjust to it just because of the similarities between fullback and tight end."

Guard Cody Whitehair, meanwhile, Mike Mayock's No. 1 rated guard, worked out at both guard and center and was "really outstanding" according to Brandt.

Whitehair, 6-foot-4, 305 pounds, earned first-team All-Big 12 honors during his senior season, capping off a career in which he started 51 games.
