5. Louisville, Thursday, March 29
Who to watch: A large number of teams are expected to be on hand to watch former Heisman winning quarterback Lamar Jackson run and go through his workouts, which will provide an even bigger stage for cornerback Jaire Alexander to make a good impression. Alexander blazed a 4.38 in the 40 at the Combine, and is projected to be a Day 2 pick. An impressive pro day could decide if that's early or late in Day 2.
Also keep an eye on: Jackson, T Geron Christian, OLB James Hearns, DE Trevon Young
4. UCF, Thursday, March 29
Who to watch: Linebacker Shaquem Griffin has deservedly stolen a lot of the headlines out of Central Florida, but defensive back Mike Hughes is a name that could interest some teams in Day 2. Hughes is versatile, but a bit raw, so teams are certainly going to put him through the ringer at his pro day.
Also keep an eye on: Griffin, TE Jordan Akins, WR Tre'Quan Smith
3. Texas-San Antonio, Wednesday, March 28
Who to watch: Defensive end Marcus Davenport had a very good Combine, but recently told reporters in attendance at UTSA's first spring practice he hoped to improve his 33.5-inch vertical jump at his pro day. The athletic traits are all there for Davenport, and a good day of field drills, in front of what will probably be a big contingent of NFL evaluators, will probably cement his status as a first-round pick.
2. Florida, Wednesday, March 28
Who to watch: One player who seems to have really helped himself in the pre-draft process is Gators defensive tackle Taven Bryan. Most projections have him being a late first-round pick. Measuring in at 6-foot-4 and 291 pounds and running a sub-5.0 40-yard dash (4.98) with a 35-inch vertical and 30 reps on the bench at the Combine certainly showed off his power and athleticism.
Also keep an eye on: WR Antonio Callaway, CB Duke Dawson, S Marcell Harris, K Eddy Pineiro, P Johnny Townsend
1. Iowa, Monday, March 26
Who to watch: James Daniels is considered one of the top interior linemen in this class, and maybe the best center available. Detroit signed veteran guard Kenny Wiggins in free agency, and also have Graham Glasgow and Joe Dahl in the mix for the center and left guard spots, but it's still a position the Lions could look to bolster in the draft.
Also keep an eye on: CB Josh Jackson, LB Josey Jewell, RB Akrum Wadley and C Sean Welsh
