#70 Mark Williams
All three of these racers (Morrison, Hateley and Williams)
had success in their racing careers.
But, I'd like to note that Williams led the AMA GNC Points
for the first few months of the 1976 season -
against the likes of Springsteen, Scott and Aldana.
Williams crashed soon after in his career and was unfortunately paralyzed from the waist down for the remainder of his life. However, it didn't really slow him down much, since he drove boats, snowmobiles and was an excellent remote control airplane operator. He passed away in 2012, but Mark remains a legend in motorcycle flat track racing history.
