It looks like Dana White has a couple ideas on combating fighters not engaging. It looks like he is pondering the thought of a smaller octagon.
 

“Actually, 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.”

 
I don't think a smaller cage will promote more action. I have been to a thousand smaller events where the cages are a lot smaller than the UFC's cage and it makes no difference. All it does is make things harder to see for the cheaper seat ticket holders. It won't bring more action. If a fighter wants to run he is going to run. If a fighter is fatigued he is going to back off. The only way it would make a difference is if the cage was 5 feet by 5 feet and they had no where to go.
 
What are your thoughts?

Yeah, I have to agree. Short of stuffing a cattle prod up the wazoo it's all about fight or flight and it makes it harder if your style is like Machida's.

i agree and thats just stupid if he makes it smaller :/

I hear you guys. I don't think it will help. It should stay the way it is. You know the saying. If it isn't broken don't fix it.
