I think I remember it being five times. Either way it was shameful. Mainly because a racist coach wanted Gable in place of Bobby. So, he forced wrestle offs over and over and over again. May well have contributed to Bobby not placing higher - wrestling the young Gable was a meat grinder.
The Dan Gable we remember from International competition was more seasoned and a real killer in 1972. Bobby wasn't beating him then.
The Russians weren't either. The story of them scouring the land looking for anyone who could beat him are true.
