More than 325 of the top prospects available in April's NFL draft descend upon Indianapolis this week for the annual combine. The coaching staffs, scouting departments and medical staffs from the league's 32 teams will join them. Over the course of six days teams will test the players physically, mentally and medically. Here's a look at the players who have a lot hanging in the balance.
Brian Brohm, QB, Louisville: Brohm was significantly overrated coming into the season, as many projected him to be a top 10 pick. He is equally underrated at the present time with some scouts thinking he could slip to the late part of Round 1.
Dre' Moore, DL, Maryland: Moore hopes to capitalize on his terrific Senior Bowl performance. He is expected to put up good numbers during his workout. Moore could gain an advantage during the interview process, as he is an engaging, bright individual.
Brandon Albert, OL, Virginia: The Virginia underclassman is considered the best interior blocker in the draft. He could move into the late part of round 1 with a good positional workout. Many teams feel he has the ability to play the all-important left tackle position in the NFL.
Vince Hall, LB, Virginia Tech: Hall was omnipresent during his Tech career, finishing with 100 tackles as a senior even after missing four games with injuries. His speed is suspect, yet a good 40 time could move him toward the top of a weak inside linebacker class.
Dwight Lowery, CB, San Jose State: Lowery quickly became one of the nation's most opportunistic cornerbacks, intercepting 13 passes after transferring to San Jose State in '06. Scouts are concerned he does not have the speed necessary to be a starter in the NFL, but fast workout times could quell that criticism.
Glenn Dorsey, DT, LSU: His recent inactivity, coupled with the outstanding play of USC's Sedrick Ellis, has people wondering which player is the top defensive tackle in the draft. Dorsey needs a big combine to quiet the doubters, many of whom thought he was the top prospect in the nation just three months ago.
Andre Woodson, QB, Kentucky: Woodson has watched his draft stock drop sharply in recent months. He will continue to fall down boards if his passing workout is anything less than stellar.
Tommy Blake, DE, TCU: Blake's troubles have been well-documented, as has his tumble down the charts. The medical staffs on hand at the combine must determine the downside risk of this one-time first-round prospect.
Mike Hart, RB, Michigan: Hart surprised many by skipping the Senior Bowl last month and has fallen behind other ball carriers who performed well in Mobile. He must run well at the combine, as many doubt he'll run faster than a 4.55 40.
Adarius Bowman, WR, Oklahoma State: Bowman did not live up to expectations last season and struggled at the Senior Bowl. He's not known for his speed and poor 40 times could further diminish his draft grade.
Devone Bess, WR, Hawaii: The playmaking receiver/return specialist is being compared to Steve Smith of the Carolina Panthers. Fast times in the 40 will push him into the middle of Round 2.
Xavier Omon, RB, NW Missouri State: Omon rushed for 7,037 yards and totaled 98 touchdowns in college. He tips the scales at 219 pounds and is expected to run the 40 in the 4.5s.
Heath Benedict, OL, Newberry: Benedict impressed scouts at the Senior Bowl, playing both tackle positions. He is an outstanding athlete and could put up the best workout numbers of any the offensive linemen at the combine.
Franklin Dunbar, OT, Middle Tennessee: The Blue Raiders left tackle is barely known to draft fans, yet he is another terrific athlete expected to impress in Indianapolis.
William Robinson, OT, San Diego St: Robinson fell under the radar screen for most of his college career. He is a physically gifted prospect who should come away from the combine as a winner.
Darrell Robertson, DE, Georgia Tech: Robertson was a disruptive force on the Tech defensive line. He has the athleticism to play outside linebacker, which scouts will be watching for.
Letroy Guion, DT, Florida State: The Seminole junior was a surprise entry to the draft, yet he is an explosive lineman whose movement skills stand out on film.
Cliff Avril, DE-OLB, Purdue: Avril played defensive line at Purdue but is projected to play linebacker at the next level. He hopes to put up linebacker-type workout numbers, including 4.6 seconds in the 40 and a vertical jump over 36 inches.
Angelo Craig, DE-OLB, Cincinnati: Craig came out of nowhere as a senior and is now poised to move into the middle rounds at the combine. His 40 time and bench press are critical.
Dominique Rodgers-Cromartie, CB, Tennessee State: Scouts think Rodgers-Cromartie played like a first rounder at the Senior Bowl. He is expected to test as well as any defensive back in Indianapolis, which could push him into the initial frame.
