Players on rise, fall after combine

Which players are moving up and down on team draft boards after the NFL combine? Mel Kiper and Todd McShay check in with six of each, with Todd handling offense and Mel handling defense. (Also check out the podcast on this topic.)

It should be noted that these are players who clearly moved up or down a grade. A great performance by Jadeveon Clowney doesn't really shift his stock; it merely confirms it.

Offense risers

WR Brandin Cooks, Oregon State: Cooks ran the fastest 40-yard dash time among wide receivers at the combine with a 4.33 and the fastest short-shuttle time (3.81 seconds) for his position group as well, backing up the playmaking ability and explosiveness he shows on tape. He is not a lock for the first round, but he has put himself in position to be taken in that range as the fourth-best receiver prospect in this class (behind Clemson's Sammy Watkins, Texas A&M's Mike Evans and USC's Marqise Lee).
