Every year come draft time "top prospects" fall while others rise. In some cases there is a causal relationship. Other times, a prospect falls for medical reasons, character questions or legitimate concerns about the players' ability to play football.
This season all three factors will be in play.
There will be players who fall because of character questions. Most of the players who fall significantly figure to be defensive players.
Jordan, the Oregon senior DE/OLB, is scheduled to miss the Senior Bowl due to a shoulder injury he suffered in October.
The result will undoubtedly be a drop in his stock, as all prospects who are unable to participate in workouts, check out in a physical or do anything physical during the spring crash harder than the Facebook IPO.
Jones is another player who faces potential hazards in his career that are health-related. He has a condition known as spinal stenosis.
As reported by redandblack.com, the severity of Jones' injury is such "that one or multiple hits could lead to severe nerve damage with possible life-threatening ramifications."
It is possible that one NFL team who views him as a top-10 prospect will overlook the health concerns, or take a bold risk believing the reward outweighs the risk.
It is more common for NFL teams to play it cautious, though, and grab such a player in the second round when expectations are lessened and the cap hit not as severe on the rookie contract.
Finally there are at least two players who appear to be seeing their draft stocks fall right now, simply based on film observation.
Until recently, Notre Dame tight end Tyler Eifert was considered the obvious No. 1 tight end on the board. Of late, though, many draft analysts have jumped on the bandwagon of Stanford tight end Zach Ertz.
Eifert is a nice option for potential NFL teams, but Ertz is more explosive and a better blocker. Expect those two players to simply flip-flop one and two.
And though corners generally climb draft boards on draft day, it seems that Mississippi State corner Johnthan Banks will do the opposite. Throughout most of the fall, Banks was thought of as an obvious first-round choice.
Scouts are souring on him as they elevate Alabama's Dee Milliner and Xavier Rhodes from Florida State. With those two presenting better athleticism, look for Banks to fall to the end of the first round come draft day.
