Here's a look at some pro day happenings from around the country and how they affect the draft stock of some big-name prospects:
RB Jonathan Dwyer appeared to be in excellent shape and ran the 40-yard dash in the 4.52-second range, which is a considerable improvement over the 4.6s he ran at the combine. Dwyer's new time should help stabilize his stock, but don't expect him to get back into the best-back-in-the-class discussion. Clemson's C.J. Spiller, Fresno State's Ryan Mathews and California's Jahvid Best ran so well at the combine that Dwyer can't catch up, and Dwyer is a second-round pick at this point.
It's also worth noting that DE Derrick Morgan did not take part in any testing but did participate in drills, and by all accounts be did nothing to hurt his standing as the top defensive end on the board. As for injured WR Demaryius Thomas, he attended the workout with a boot on his surgically repaired foot and was walking without crutches.
Sliding WR Brandon LaFell ran two 40s with a strained hamstring and posted 4.55 seconds both times, an improvement over the low-4.6 times he posted at the combine but still not fast enough to give his stock a much-needed boost. In addition, LaFell missed the Senior Bowl with a knee injury and now is dealing with the hamstring issue, and there are two ways teams can analyze this information.
The first is that the injuries may be slowing LaFell down and he's showing some toughness by working out. The second is that minor injuries are starting to pile up. But even if teams take the first approach, the times are still a concern because LaFell doesn't show great top-end speed on film and teams don't know how much the injury is slowing him. He entered the season as our top-rated senior wideout and has looked like a first-round pick on film, but inconsistent effort and sloppy route-running during the season combined with his disappointing times will likely make him a third-round pick.
RB Charles Scott ran a high 4.6 at the combine and improved to 4.53 at his pro day, a good time for a bigger back (5-foot-11, 232 pounds) and one that should solidify his standing in the fourth round. S Chad Jones remains a third-rounder after slightly improving his combine numbers. S/OLB Harry Coleman improved from 4.65 at the combine to 4.45 at pro day, and teams will be digging deeper to find out what caused such a discrepancy.
CB Chris Hawkins improved his 40 time to 4.40, and that could help his stock because not standing on his mid-4.4s from the combine showed teams his willingness to compete. Hawkins is lean (5-11, 186 pounds) and needs to add bulk, and because he doesn't have great hip fluidity Hawkins is not a top-tier corner prospect. However, as a two-year starter in the SEC who has the natural ability to play in the NFL, he should be a late-round pick.
WR Chris Mitchell caught just 24 passes for 239 yards and two touchdowns during his time at LSU, so don't feel bad if you don't recognize the name. Still, Mitchell may have earned himself an invite to a training camp as a rookie free agent and a team may even take a chance on him in the seventh round. At 6-1 and 189 pounds, he ran 40-yard dashes in 4.42 and 4.46 seconds. He also has good-sized hands (9.4 inches) and recorded a 37.4-inch vertical jump.
