Shamarko Thomas had a stellar combine this year in Indy. Though he is smaller than the average SS, CBS Sports has him as a second or third round draft pick. This is their analysis:

Strengths: Obviously shorter than ideal but possesses a very stout frame. Highly aggressive defender who uses his natural leverage advantage to slip through cracks in blocking fronts and prove a nuisance around the line of scrimmage. Thomas plays the game with reckless abandon and loves to throw his body around on the field, seeking big hits against the ballcarrier. Sent off the edge as a pass rusher, showing the lateral agility to avoid blocks from running backs and excellent closing speed. Good lateral agility and speed in coverage. Reportedly was timed at 4.26 seconds in the 40-yard dash during Syracuse's junior timing day.

Weaknesses: Obvious size limitations, though these concerns ironically, show up most when he's away from the game's biggest players. Makes most of his plays near the line of scrimmage. Thomas plays too aggressive and too often bites on fakes, finding himself constantly playing from behind, where his height and lack of arm length can be a real detriment. Has a tendency to lead with his shoulder on his hits, resulting in some big pops but also some slipped tackles.
