One historic victory and he's HOF worthy? It's the Hall of Fame, not the Hall of Single Achievements. I applaud Dough Williams for what he said, but for the most part he was a mediocre QB who spent a large part of his career in the USFL.
Namath was one of the best QB's of his era, the stats from that era you can not compare to todays stats. Williams was not one of the best QB of his era. He was middle of the pack at best. Even when he was young and in Tampa and had some success there.
I am a Doug Williams fan, but he's got no business being in the HOF based on that one win.
