While the NFL combine has historically been an opportunity for the athletically-gifted players to boost their stock headed into the draft, some players actually drop down draft boards based on their athleticism (or lack thereof).
There is a tremendous number of high-octane prospects on the defensive side of the ball this season, which makes it tough for those who aren't explosive defensive players.
On the other side, a couple of receivers have the potential to be solid pros but won't exactly overwhelm at the combine, which figures to hurt their draft stock.
Here's a look at the top players I see falling down draft boards after the 2013 NFL combine.
Keenan Allen, WR, Cal
Keenan Allen has solid size and hands, and he has decent top-end speed, but he doesn't possess outstanding quickness, burst or elusiveness.
That figures to show during the combine and it's one of the reasons why many have dropped him below Tennessee's Cordarrelle Patterson on their draft boards.
Alex Okafor, DE, Texas
Alex Okafor's strength and length is impressive, but those teams looking for a speed-rusher off the edge may be disappointed.
If you are looking for a well-rounded player with a high motor who can be an asset against the run and the pass, Okafor isn't a bad pick. But if you are expecting him to be an explosive edge-rusher, you have another thing coming.
DeAndre Hopkins, WR, Clemson
I actually like DeAndre Hopkins, but that doesn't mean he won't drop after the combine.
Hopkins is an impressive, fluid route-runner with solid hands and a killer instinct, but that doesn't show at the combine. He doesn't have great height (6'1") and he's not eye-opening when it comes to his top-end speed.
Then again, there were similar concerns about Reggie Wayne and look how he turned out. In the end, Hopkins could be a steal in the second round.
