Or Erics Stokes, who ran a 4.25 40, vs Hill's 4.29. MVS is pretty fast at 4.37 (and crazy fast for his height), but not Stokes fast.
I just looked up Usain Bolt's 40 time, he ran a 4.22 apparently, so just a little faster than Stokes. That's incredible. Of course Bolt is more of a 100/200m guy with top end speed over longer distances, but that's still pretty neat.
And just for fun, Don Beebe ran a 4.21! I wonder how many NFL players Don could outrun at age 56...
