It's been a tough few days for the Arizona State Sun Devils at the NFL Scouting Combine.

Brock Osweiler, whose draft stock is rising quickly, elected not to participate in any drills, opting to wait for March 30th.

Center Garth Gerhart had an average performance, that did not seem to have too large an effect on his draft stock. On Sunday, wide receiver Gerell Robinson had an uneven performance, in which his 4.62 official 40-yard dash time did nothing to address his biggest concern.

Monday saw the defensive players go to work. Defensive end Jamaar Jarrett, like Gerhart, was a fringe prospect whose underwhelming performance did him no favors. But the biggest and saddest story was the terrible showing of linebacker Vontaze Burfict, whose 40-yard time (5.09 seconds) and broad jump (105 inches) were dead last among all linebackers, and his vertical leap (30 inches) was next-to-last.

But the day ended on a great note, as cornerback Omar Bolden, coming back from a torn ACL that forced him to miss the entire 2011 season, led all of the 46 participating defensive backs with 24 repetitions of 225 pounds in the bench press.

Congrats, Omar. Keep making ASU proud.
