"We've been talking about making the Octagon smaller. We're considering making it smaller. [UFC matchmaker] Joe Silva wants it. I think he wants to turn the thing into a [expletive] bathtub. Have them fight in a little tollbooth." - Dana White
I think thats way more benefit to the wrestlers although it would make for less running away. i don't really want to see them shrink it down too much if they do.
