I can understand why Ngannou gassed. It could be that he bought into his own hype with the UFC helping inflate that, it could be poor conditioning, it could be the excitement of being in the big fight that has drained the gas tank of many fighters who weren't known for having a bad gas tank, or it could be a combination of those. In the past we've seen fighters who aren't known for having bad gas tanks having their cardio drained in the 1st round and after a fairly low-key round. So, I do believe the excitement of being in the big fight/title fight can gas people out. I believe that is partially what happened to Francis. Sure Ngannou was throwing full power punches at Stipe but he wasn't throwing a ton of them. I thought there was a name for it, but I think a lot of what happened to Ngannou was in fact the excitement of being in a title fight caused him to have a drastic cardio drain. So, if that's what happened to Ngannou, what happened to Stipe? Stipe wasn't throwing a ton of strikes standing, got Ngannou to the ground easy, and threw almost no ground and pound, content on laying on Ngannou and throwing a punch or two when the ref warned him he needed to be active otherwise he'd get stood up. I mean Mike Russow was throwing more vicious GnP on Todd Duffee and in higher volume. Obviously Stipe had 2 title defenses already and wasn't gonna gas being in a title fight. Stipe also appeared to be almost gassed by the 2nd round and Stipe didn't take too many hits from Ngannou that could have wore him out either. So, how did Stipe gas by laying on Ngannou and throwing some of the weakest GnP of all time?
