Nolan IV played at Hutch Juco about 5 years ago, was around 6'1" 2G, he was a pretty solid player, probably not big enough or athletic enough at that position to be considered high major, I also think he had some academic troubles, went on to D2 Midwestern St. and fared pretty well there.
The google machine tells me he's bounced around some Int'l pro leagues and has seen some brief action in the D league.
Tough blow for the entire Richardson clan, 47 is awful damn young to be dying of natural causes. R.I.P. NR III.
