5. Oklahoma State, Thursday, March 15

Who to watch: When people talk about this year's quarterback class, the names talked about first and foremost are Sam Darnold, Josh Allen, Josh Rosen, Baker Mayfield and Lamar Jackson. Oklahoma State's Mason Rudolph is considered the top of the next wave of passers. He'll try to prove at his pro day Thursday he belongs in the conversation along with the other five. He threw for over 4,000 yards last year with 28 touchdowns and just four picks.

Also keep an eye on: WR James Washington, WR Marcell Ateman, S Tre Flowers and WR Chris Lacy

**4. Oregon, Thursday, March 15

**

Who to watch: Running back Royce Freeman rushed for at least 1,300 yards and 16 touchdowns in three of his four seasons at Oregon. He measured in at 229 pounds at the Combine, and ran the 40 in 4.54. He's among those backs considered to be a lock for Day 2 of the draft. Could a strong Pro Day and a sub-4.5-seconds in the 40 sneak him into the late Day 1 conversation?

Also keep an eye on: LS Tanner Carew and T Tyrell Crosby

3. Virginia Tech, Wednesday, March 14

Who to watch: How about the Edmunds brothers? The younger (by a year) Tremaine is a versatile linebacker with some sub-package rush potential based off his size (6-5, 253). The older Terrell also has terrific size (6-2, 220) for the safety position. He showed freakish athletic traits at the Combine with a 40-yard dash time of 4.47, a vertical of 41.5 inches, and a broad jump of 134 inches. Teams will be very interested in his on-field drill work at this pro day.

Also keep an eye on: WR Cam Phillips, DT Tim Settle, CB Greg Stroman and G Wyatt Teller

2. Oklahoma, Wednesday, March 14

Who to watch: Tackle Orlando Brown had such a bad Combine from a testing perspective that most teams probably went back and watched more tape on him. His size (6-8, 345) and game tape are better than his numbers would indicate. One of the more troubling parts of his Combine workout is when coaches were questioning his effort in drills. He needs a better pro day performance than he had Combine.

Also keep an eye on: QB Baker Mayfield, TE Mark Andrews, RB Dimitri Flowers, OLB Ogbonnia Okoronkwo and CB Jordan Thomas

1. UCLA, Thursday, March 15

Who to watch: All eyes will be on the 50 or so throws quarterback Josh Rosen performs for scouts at UCLA's pro day. Josh Allen had a better Combine throwing the football than Rosen did. Rosen was supposed to be the more accurate of the two, but it was Allen who showed that off more in Indianapolis. In a controlled environment, with receivers he's familiar with, will Rosen show off his accuracy better for scouts and coaches?

Also keep an eye on: DE Matt Dickerson, WR Jordan Lasley, T Kolton Miller, C Scott Quessenberry and LB Kenny Young
