If grappling ever becomes olympic it will be the World United Wrestling version. First it's way more exciting than the ibjjf rules and second they got close ties to the olympic committee.
Let's be real as of today IBJJF matches are soporific 90% of the time. Plus nobody wants to see people doing this at the olympics :
BJJ guys have the least shame out of every single combat sport that exists. Butt scooting, 69ing other men, intense teabags. All with no shame.
