Hi guys this is my first post here. I felt compelled to join as a basketball (and football) fan who is intrigued by the league's current interest in American college athletes. I was checking the combine results here:

The guys that might be of interest (besides Cox):
Justin Wesley: the best "absolute vertical jump" (bearing in mind he's probably a fair bit shorter than Cox, so his vertical by itself would be far greater than Cox's), best 20 metre sprint, and 4th best in agility
Marvin Baynham: 6th in "absolute" vertical, 2nd in 20 metre sprint, best in agility
Jay Smith: 4th in 20 metre sprint, 1st in repeat sprint, 5th in 3km time trial
Drew Barham: 3rd in agility, 5th in repeat sprint, 1st in 3km time trial
Checking their ages:

Of course the other factor in all of this is their own keenness and willingness to try their hand at a foreign sport on the other side of the world. From memory I don't think US recruits Eric Wallace, Jason Holmes and Patrick Mitchell necessarily tested the best out of all the athletes at their combines so presumably other factors like attitude came into play.
