Glover got tired? He was still taking Page down and landing more GnP than a lot of wrestlers do in a whole fight. He ended the fight on top with relentless GnP....
How does that mean he got tired? Does he have the best cardio in the division? No. But it is pretty decent. And it was pretty good last night when you see him pouring it on at the end of the 3rd round after a back and forth brawl getting hit by a power puncher.
