With the combine and almost every "Pro Day" behind us, it's time to see which draft prospects, most of all which 1st round prospects, have been hurt by their performances and the performances of those around them.  The buzz from bowl season and all-star games have cooled, so now teams are judging these guys on measurables, attitude, and professionalism along with game performance.  Here is a list of some of the bigger names whose draft stock has slid of late:

1.    Vince Young, QB, Texas: This does not make much sense to me, but I expected it.  Young's stock would never be higher than it was following the Rose Bowl.  The only place it could go was down, as draft "experts" would start to doubt his throwing motion, intelligence, arm strength, and his ability to read defenses and sure enough, it has happened.  Young's first mistake was to hire Major Adams as his agent.  A criminal defense attorney who has only negotiated one prior NFL contract (Eagles' safety Michael Lewis), Adams has not marketed Young nor prepared Young for the rigors of the NFL Draft season.  This was evidenced by Young's low Wonderlic score, failure to bring a suit to the Longhorns' White House visit, and overall non-existence in the public eye since the Rose Bowl.  Young's stock would have maintained had his Wonderlic been a few points higher and had he participated in QB drills with Cutler at the combine.  His failure to do so has him sliding from a top-3 pick to a likely 6-10 pick which essentially means Young has already lost multiple millions of dollars in guaranteed money.  His Pro-Day on the 22nd helped some, but there are still doubts about his passing ability and some scouts were disappointed in his 40-time (4.58).

2.    Chad Greenway, LB, Iowa: Greenway was viewed as possibly the top OLB prospect in the draft after the college football season.  He was viewed as extremely athletic, strong, passionate, and gritty.  While no one questions his passion or grittiness now, there are some big questions about his strength and speed.  Many expected him to run in the 4.5 region, but at the combine, he turned in a fairly pedestrian 4.78.  Combine that with only 16 reps in the bench press, and you can see why these questions have risen.  The other agility drills did not treat Greenway as well as many expected too, so he continues to slide in the eyes of scouts and draft gurus.  He has not been helped by the emergence of others like Ernie Sims, Thomas Howard, Kamerion Wimbley, etc who have displayed freak athleticism and have the production to match it.  Here is betting that Greenway will be a late 1st rounder as opposed to the potential top-15 pick many projected him to be a couple months ago.

3.    Santonio Holmes, WR, Ohio State: Widely viewed as the top-WR prospect when he declared for the draft in January, Holmes has been passed by Chad Jackson in the eyes of many associated with the draft.  On a fast surface at his Pro Day, Holmes ran a 4.38 40 which is very fast, but still disappointed some in attendance.  Combine that with his lack of height and his weight (179 lbs.), and you can see why scouts have some doubts.  Chad Jackson's exponential rise over the last couple of months has also caused Holmes' stock to fall.  Jackson is bigger, stronger, and faster than Holmes and has put his hands on display in the College All-Star challenge and at the combine. 

4.    Marcedes Lewis, TE, UCLA: Lewis had a great senior season, but his poor showing at the Senior Bowl and his mediocre combine plus the freakish performance of Vernon Davis of Maryland have created a significant gap between the two.  Once a lock first-rounder, Lewis is now a mid-2nd round pick.

5.    Jonathan Scott, OT, Texas: Scott has never been a mauler along the offensive line, but his recent showings at the combine, Senior Bowl, and the UT Pro Day have put a finesse tag on him.  With only 17 reps on the bench press, Scott's ability to get separation from defenders and move them has been put in question.  Also, his limited athleticism have led to doubts about even being a finesse blocker.  Essentially, Scott went from the 2nd best OT prospect in the draft to the 4th or 5th. 

6.    Kai Parham, LB, Virginia: Parham was a heralded high school recruit, part of Al Groh's heralded 2002 one that included Ahmad Brooks.  After a solid college career, Parham made the choice to leave UVA early, and it looks like that might have been a poor one to make.  Supposedly a gifted athlete, Parham ran a pedestrian 4.91 and 4.98 at his recent Pro Day, showed limited explosiveness, and did not perform well in the position drills.  Once jockeying for position as the top MLB prospect in the draft, Parham will be luck to be a 4th-5th rounder now.  This slide is very reminiscent of LaMarcus McDonald, the former TCU linebacker who ran a 4.99 at his Pro Day and went from a late 2nd rounder to not even being drafted.

7.    Jimmy Williams, CB/S Virginia Tech: Williams has always been thought of as a "tweener" CB/S combo player who has the ability to be successful at both positions.  A safety when he first arrived on campus, Williams filled the gaping hole left by DeAngelo Hall and more than met the task.  His performance translated into him being a top-10 pick.  However, his failure to participate at the combine while almost every other DB prospect did combined with his poor interviewing and mediocre Pro Day have him going from the top DB prospect to perhaps the 4th.  Williams should have run in Indianapolis, as many from Tye Hill to Michael Huff to Jonathan Joseph ripped off blistering times on the RCA dome turf.  Then during interview sessions, Williams maintained that he was a safety and not a corner, which turned some teams off.  He was very defiant against playing corner in the NFL as a whole, perhaps displaying doubts about his own ability.  No matter what the motive for his standoffishness, Williams made himself less marketable, versatile, and desirable in just a matter of days.  He will still be a first round pick, but he lost himself the shot of getting top-10 money and now is vying with Hill, Joseph, and Ko Simpson as the next DBs off the board. 

With a month left until the draft, this list could still grow, but hopefully for the names above, it will shrink.  Private workouts can change the downward spiral that many of these players are experiencing right now.  Vince Young has already scheduled private workouts with the Ravens, Dolphins, Texans, and Jets.  This is where the players' agents come into play, as it is now their job to spin their clients' performances into something positive and make these guys more attractive to NFL teams.  A move from the #5 pick in the draft to the #15 pick is a matter of tens of millions in guaranteed money and the prestige that goes with it.  Remember, it's not over till it's over.
