Roy Williams, WR, was a world class sprinter in HS. To you point.
Well Roy was pretty fast but I think his high school best was 10.48.. which is movin.. but not quite world class. Plus it happened in Texas and frankly I am always skeptical of some of the times that come out of Texas high schools. But usually it's just because Texas used to have (and still might have) that ridiculous rule that allowed kids to compete in high school sports up to like age 23 if they were diagnosed with a "learning disability." The number of 20 and 21 year old men out there dominating teenagers across the Texas high school landscape used to be astounding and disgusting. I think they have mostly fixed that but back in the day it was rampant.
I remember Billy Sims turning 20 the year he graduated high school.
This all reminds me of Mychal Thompson's high school hoops team in Miami which featured Mychal Thompson (yes Klay's dad and former Laker great) and four grown *** men from the Bahamas who ran through like a 35-0 season in the mid 70's. Miami Jackson.. the media called them "The Jackson Five." When the scam was uncovered they had to forfeit all 35 wins.. I can't remember but I think the team they beat for the state championship would eventually be crowned the champs.. like five years later. Big damn deal huh..
