Where was Herschel? He was a world class sprinter also.
Walker was indeed a burner, particularly for his size.
A few other guys they missed, not all of whom were particularly good football players, but definitely world-class sprinters and worthy of consideration of top ten status:
Earl McCulloch--world record holder in the 120 yard hurdles (run in yards back in the day), member of USC's world record 440 relay (also in yards back then)
Renaldo Nehemiah--world record holder in the 110 meter hurdles
Jim Hines--1968 Olympic Gold Medalist and world record holder in the 100 meters--played a couple of years in the NFL, caught a handful of passes.
O.J. Simpson--another member of USC's world record 440 relay, teammate of Earl McCulloch
Homer Jones--the prototype modern receiver; big (6-2, 205) and fast (9.3 in the 100 yard dash when 9.1 was the world record). And invented the TD spike!
Tony Simmons--10.2 100 meters in college, IIRC, played a few years for the Pats and other teams.
Couple of other Cowboys of note, both Mel Renfro and Mike Gaechter were members of University of Oregon's 1962 world record setting 440 relay. I'd also submit that Tony Dorsett was as fast as any running back I've ever seen. But without doubt, Bob Hayes is the fastest man to ever play pro football (who could actually play).
