He will retire Rampage at this point 
AJ would take Rampage down, or at least try to. He's way more athletic at this point. And if you watch his fights with dangerous strikers, even when he wins by ko, he usually wrestles the guy a while (Manuwa, Belfort, Hardy, Arlovski I think). AJ probably catches Rampage a lot like he caught Manuwa 
disbeliever - Rampage would diePride never die
TheBigRedOne -He looked horrible n gassed out in bader fight, king mo fight, the griffen fight, any fight that passed the 2nd round lolmandingo1987 - Yeah it would be the battle of the cardio. Who gasses first
When has Rampage ever gassed?
Page had better prime cardio tha. Rumble but page is old rumble would kill him
Fedor vs Rumble? How would that fight go down? Damn that would be a crazy wild fight.
Manuwa v Rampage please
Fapping2FabersButtChin - Manuwa v Rampage please

orcus -He has better cardio than johnson does.zackthewop - Rampage would counter johnsons huge looping punches all day.
It would come down to who gassed first. Id say rampage has a good chance here.
Yeah Rampage has great cardio and tight straight punches.
I think johnson throws huge looping punches like chuck and rampage has good head movement and great counter punches. Im not saying he would be the favorite but he would be a live dog and id pick him.
orcus -What you did there, I see itzackthewop - Rampage would counter johnsons huge looping punches all day.
It would come down to who gassed first. Id say rampage has a good chance here.
