What? DC subbed him like halfway through rd 3. And Rumble was DONE. Absolutely and completely gassed.
I'm not saying he might not pace himself better this time, but you have realize DC just isn't gonna stand with Rumble again. He's gonna **try** to get his grind on asap. Which means closing distance. Which means he either gets his hands on Rumble and takes him down and works him there (which will tax Rumble's gas tank even worse than throwing bombs) or he's gonna eat one of Rumble's nuclear warheads that he has on the end of his arms and probably not survive this time.
Either way, this thing going 25 minutes is really unlikely. Not impossible obviously, but I don't see value in +320 at all.
