after some digging, i found out who those two other White sprinters running alongside Smith are.
Wayne Sherbahn, formerly of Indiana Tech, is trying to make a go of it as a professional sprinter after suffering a devastating hamstring injury and broken arm that cost him a lot of time during his collegiate eligibility (he's apparently finishing up a degree in criminal justice). He has a personal best of 10.25 (and a slightly windy 10.11) in the 100, and the 6.52 above is his new pr in the 60. He was a multiple-time All-American at the NAIA level of track and field.
the other athlete is Seth Boomsma, formerly a sprinter for Dakota State. he's also a multiple-time All-American at the NAIA level and has obviously not given up on the dream yet.
so, there you have three elite sprinters at the national level that all attended NAIA schools (Blake Smith went to Southeast Missouri).
Interestingly enough, Boomsma was by far the fastest of the trio in high school, clocking a (no wind indicated) 10.70 as a senior. Smith was recruited to college as a long jumper. Sherbahn's best-ever time in high school was only 11.09. I think there's something to learn there, for those who have eyes to see ...
