He was a very foolish man all told
He'd had a very successful career and unlike many former sports stars maintained a lucrative post-football life with sponsorship, acting, TV commentating, and all-round good guy who was very popular in both black and white American show-biz life.
But he threw that all away by beating his wife over the years who then divorced him, then eventually killing her and Ron Goldman in a fit of rage.
He had it all but something went wrong somewhere.
