Scout.com currently ranks Simpson as the No. 6 safety prospect available in the 2006 NFL Draft.
The Cowboys had a significant need at the free safety position entering free agency, but the team signed veteran Marcus Coleman to assist last year's starter Keith Davis in 2006.
Still, the team would like to get younger at the position while also upgrading its talent.
As a natural ball-hawk who consistently proved himself in one of the toughest conferences in America, Simpson fits that role and would offer tremendous upside and significant value as a potential second round pick.
Simpson played just two years of college football at South Carolina, but earned SEC Freshman of the Year honors in his first season and an All-American honors last year.
Projected as a free safety at the NFL level, some scouts are concerned about his pure speed, but his play-making skills were unquestioned in college.
Full Name: Ko Simpson School: South Carolina Pos: S
Ht: 6-1 Wt: 209 40: 4.47 Year: 3So
Bio: All-Conference and All-American last year after 103/1/9. Freshman totals included 61/6/6 and named SEC Freshman of the Year. Graduated from high school in '03.
Pos: Large, forceful safety best in a zone system. Fires up the field, defeats blocks and strong at the point. Diagnoses the action, takes good angles to the play and displays suddenness to his game. Possesses a good break to the pass and works well with cornerbacks. Solid range in centerfield and displays good ball skills.
Neg: More of a loping runner who takes a while to get it going. Gets caught up the field and has tackles broken. Does not display a sense of timing.
Analysis: An imposing defender at free safety, Simpson offers terrific upside for the next level. Should be a productive starter in the NFL once he improves the details of his game.
