Radnich was the one he admitted who lost a bet to Riggs on who could make the most free throws out of a 100,back in the 1980's. Only Riggs the showman used a football. So,to make it short the older con artist won over the younger one who said "I had to have my wife take money out of her account to pay Riggs the $250.
What got weird is...Radnich said he dated Riggs daughter after that twice. So,was that while married? Or he got divorced 15 year later and gave her a call? He didn't explain that huge gap.
Family man played fast and loose with woman sounds like.
