Lets have a look at the best combine numbers since 2001:
No Step Vert:
Nick Young (2007) - 39.5 inches
Max Vert:
Kenny Gregory (2001) - 45.5 inches.
Sprint:
Cookie Belcher (2001) - 2.91 seconds
Agility Test:
Jamison Brewer (2001) - 9.65 seconds
Bench:
Jason Keep (2003) - 27 repetitions
Unless someone wants to argue that those 5 are superstars, perhaps we should look at something other than combine numbers to determine who's the best player ?
And yes, there really was a player named Cookie Belcher (worst name ever ?).
