That loss changed bas into a mma fighter tho. He wasnt going to lose by leglock again and started training bjj and grappling. So in a way we can thank ken for creating the bas that came to be.
I absolutely
love Bas, he's one of my all-time favorite fighters along with Ken, but this is a ridiculous myth perpetuated by Bas for the sake of his ego. Prior to his
first fight with Ken, Bas trained diligently for six months on his submissions with Funaki, who also cornered Bas for that fight. He also tells that stupid story during his commentary on his second fight with Ken about being taught the "wrong" kneebar defense as if that's why Ken tapped him, yet in his fight with Frank three months prior to that rematch with Ken he was using (hence clearly knew) the "right" kneebar defense.
In short: Bas wasn't the grappling neophyte he'd like people to think he was. Ken was just better than him.
