Senior Bowl Risers and Sliders

MOBILE, Ala. -- Today was the North's final opportunity to impress NFL scouts here. Wednesday is always the most important day of the week at the Senior Bowl and the practices are heavily attended. Several players took hold of the chance to showcase their skills.

Joe Flacco, QB, Delaware: Flacco is the most physically gifted passer at the Senior Bowl and he showed why today. He effortlessly tossed the deep passes and put speed on the outs, two throws he must complete at the next level.

Fred Davis, TE, USC: Davis plays like a receiver in a tight end's body. He runs good routes, beats defenders down the field and displays reliable hands.

Trevor Laws, DT, Notre Dame: Laws does not possess top NFL dimensions -- he measures just 6-foot, 300 pounds -- yet there is a lot to like about his game. He has played with a non-stop motor every day and is constantly around the ball.

Xavier Adibi, LB, Virginia Tech: Adibi's athleticism is apparent as he displays speed and range on the field. He stood out in morning drills before making several good plays during the scrimmage.

Kellen Davis, TE, Michigan State: Davis is another outstanding athlete who flashed dominance in all aspects of the tight end position today. He's not a finished product, but scouts love his upside potential.

Jordy Nelson, WR, Kansas State: Nelson is drawing comparisons to Anthony Gonzalez, the Colts' first-round pick from last year. He's a natural receiver with a terrific head on his shoulders. Nelson made a number of deep receptions today.

Jason Jones, DE, Eastern Michigan: Jones rebounded well after two uninspired practices. He threw a few nice moves on Ohio State's Kirk Barton and got a lot of penetration this morning.

Dan Connor, LB, Penn State: Connor has been one of the hardest hitting players all week. He's shown himself to be a smart football player who will be a reliable run defender in the NFL.

Terrence Wheatley, CB, Colorado: Whealtey was over matched for most of the day, getting beat by large receivers and outrun by fast pass catchers. He dropped a sure interception during the scrimmage.

Bruce Davis, LB, UCLA: Davis, a defensive end in college, was used extensively at linebacker and the results were poor. He's a solid athlete, but at times he looked lost on the field and struggled handling assignments.

Chris Ellis, DE, Virginia Tech: Ellis was a pass rush specialist for the Hokies, but he has had little success here. He was handled lining up in a three-point stance and the results weren't much better when he stood over tackle as a rush linebacker.

Marcus Smith, WR, New Mexico: Scouts were anticipating Smith's performance, as his production (91 receptions in '07) and size (6-1, 214 pounds) are enticing. But he's been a letdown -- dropping several easy receptions today -- and he does not play to his size.

• Injuries are starting to mount at the Senior Bowl. Owen Schmitt of West Virginia looked good in morning drills, but the fullback later injured his knee and left the field. Michigan's Shawn Crable also left the field with a lower leg injury. Limas Sweed, the Texas receiver on the South squad, slightly reinjured his wrist and will no longer practice or play. Sweed originally hurt his wrist in October and surgery was required to repair the damage.
