The NFL Combine is a place for top talents to show their athleticism and prove that they are worth of a first-round pick, but also for little known players to showcase their potential.
However players' stock can be hurt at the Combine with a an injury or a poor showing.
The 2012 Combine is underway and players are starting to pour into Indianapolis to showcase their talents in front of NFL coaches, scouts and GM's.
Players will compete in such drills as the 40-yard dash, broad jump, shuttle run and bench press, and their performance in these could essentially determine if they are a first rounder or fall to later rounds.
At the 2012 Combine, one of the players whose stock could fall the most is Alshon Jeffery.
Much has been made about his weight issues and his work ethic on and off the field. Jeffery was thought to be around 250 pounds by the end of his season last year but has reportedly slimmed down to 220 pounds.
According to Aaron Wilson of Scout.com, Jeffery is down to 217 to 220 pounds and will look to run a 4.5 in the 40-yard dash.
Even if Jeffery has slimmed down, questions still remain on whether or not he can keep it off and if he has enough burst to get separate from defenders at the next level.
If Jeffery shows he doesn't have decent speed or agility, his stock could fall enough to put him out of the first round.
There is no question Jeffery put up superb numbers in a shaky South Carolina offense, but scouts wonder if it can translate to the next level.
Mike Mayock of NFL.com said this about Jeffery:
"Alshon Jeffery does not separate. What those guys run [at the Combine] is important. He needs to run somewhere in those mid-4.5s...Big and fast is good. Big and slow is bad. Bottom line is, he has got to run well."
Mayock does not have a first-round grade on Jeffery either, putting Justin Blackmon, Michael Floyd, Kendall Wright and Reuben Randle all ahead of Jeffery at the wide receiver position.
Jeffery must wow at the Combine to put himself ahead of those other wide outs in order to crack the first round.
Otherwise, a talent thought to be a Top 10 pick after the 2011 season, may drop into the second round in the 2012 NFL Draft.
