A blackbelt subbing a 1-0 wrestler is not an impressive win. And that version of Nog would have been beaten by a lot of fighters.
Not impressive only of you don't have a brain to realize that wrestler is a UFC champion who seems prepared to hold that belt for a long time or a functioning pair of eyes to just see how good Lesnar actually is as a fighter.
He wasn't the UFC champ at the time. He was a big, athletic wrestler with barely any fighting experience and a rudimentary sub defense. He just didn't have the training and experience to survive on the ground with a bjj black belt. It's similar to Enson subbing Randy, only that Randy had 4 times the experience when he first lost by submission.
He can't be Kongo????? What will happen when it gets to the ground???? Oh yes Kongo is a great ground fighter from his back... Kongo has only 2 he dose better then Mir. 1). Stand up strike... 2) Ball Shots.
