Here's TSN's scouting report on Clemons entering the draft last year to refresh your memory on him. We drafted him in the 5th round out of Clemson.
Strengths:http://www.phinfever.com/newsite/index. ... 74&Itemid=
Is an athletic safety with quick feet, which enable him to accelerate to full speed fast. Once he gets to full speed, has the playing speed to chase down plays in pursuit. Consistently flies up the field quickly and aggressively in run support, can avoid blockers and is willing to make violent hits. When he stays under control, keeps his knees bent and stays over his feet, has flashed the ability to drive up into the ballcarrier to make strong and sound tackles. Flashes the quickness to plant, drive and close fast on passes in front of him and down the seam, then gets there in time to deliver a hard blow right as the ball arrives to break up the pass. Has the speed and athleticism to cover tight ends well in tight man-to-man coverage.
Is a better athlete than football player and does not produce to his level of talent consistently. Is overly aggressive, which leads to him attacking plays in front of him and getting beaten by plays behind him. Will jump on play-action fakes, allowing the receiver to get behind him, and he cannot recover to get back into good coverage position. Also jumps on the QB's pump-fakes and cannot recover when the receiver zips by him. Has bad tackling technique despite flashing the ability to be a good tackler. Has a bad habit of stopping his feet and bending at the waist when he tries to tackle and ends up missing as many tackles as he makes. Won't be a good special teams player in the NFL unless he improves his tackling.
Clemons was not highly productive in college, making big plays but then disappearing for long stretches. However, an excellent Combine has many coaches and GMs saying he has the physical tools to develop, which likely will get him drafted in the middle rounds after playing like he'd be an undrafted free agent in '08.
