I don't know why anyone would listen to Arum... he is full of shit about everything.
MMA, in general, isn't my cup of tea. I like the strikers and that is why I will never come in MMA thread talking big shit. I don't know much about the sport. I gave it a few tries... but it isn't for me.
I might fuck with it more if they broke up the ground shit more often since a lot of what I've seen doesn't seem to go anywhere, but with the ground game being an important part of the real fight element... I don't know how that is possible. So I'll stay in my lane.
If you don't like it... move on...
