Originally posted by carver9WWH was already operating at his angriest(and therefore strongest) levels up to that point -- his ability to mentally snap in times of duress and become stronger still(ie. WBH) doesn't change this.
It's basically no argument against Hulk holding back or not since he got much stronger after his fight against Jugs.
Point being: the most powerful Hulk we had ever seen at the time was apparently unable to incapacitate Juggernaut, like he incapacitated so many others... and there is really no reason to think that Hulk would have been intentionally holding back the strength he had access to(at the time) against an opponent like Juggy.
...Unless, of course, you're suggesting that Hulk would've needed to enter 'World-Breaker-mode' to definitively overpower Juggernaut? In which case... Okay?
