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:

Georgia Tech</h3
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.
