Defensive linemen and linebackers worked out on the Lucas Oil Stadium field Monday on the fifth day of the NFL Combine. So who did well, and who struggled? Here are the day's risers and fallers:
RISER: Aaron Donald, DT, Pittsburgh
Donald posted impressive measurables on Monday. His 4.68 40 was fifth-fastest among defensive linemen, and his 7.11 three-cone drill was fourth-fastest. He also did 35 reps on the bench press on Sunday, second-highest among defensive linemen. He doesn't have great size (6-1, 285 pounds), but his Combine numbers added with his excellent production in 2013 should help him secure a spot in the first round of the draft.
FALLER: Michael Sam, DE, Missouri
Sam was remarkably average on Monday. He ran a 4.91 40 and a 7.80 three-cone, and posted a 25 1/2-inch vertical jump. (He also posted 17 reps on the bench press on Sunday, tied for second-worst among defensive linemen.) Sam also looked a little stiff at times in positional drills, reinforcing the belief that he is strictly suited as a rotational pass rusher. He's slated to go somewhere on the third day of the draft, probably somewhere around the fifth round.
RISER: Telvin Smith, LB, Florida State
Smith showed great speed on Monday, clocking a 4.52 in the 40. That time was second-fastest among linebackers, .01 second off Kevin Pierre-Louis' time. He may end up becoming a safety at the next level because of his lack of size (6-1, 218 pounds), but he has the ability and quickness to remain on the weak side.
FALLER: Trent Murphy, DE/LB, Stanford
Murphy worked out with the linebackers on Monday and was unimpressive all around. He clocked a 4.86 40 (to go with his 19 bench press reps on Sunday) and had a few mistakes in positional drills. He's a second-rounder at this stage.
RISER: Khalil Mack, LB, Buffalo
Mack solidified his status as the draft's top linebacker. He ran a 4.65 40 (.01 second faster than Anthony Barr), had a vertical jump of 40 inches and a broad jump of 128 inches, and looked fluid in drills. He shouldn't fall outside of the top 10 in May's draft.
