I suppose that makes sense. It was still kind of annoying though. Him also saying "Glover taking it to the ground now cause he doesn't want to take any more chances." was weird too. I think it had more to do with him throwing so many punches and landing nearly all of them. It would be naive to think that his arms weren't tired from that assault. Before that punch, Glover was dominating the fight on the feet and on the ground.
Before and after that punch landed he was dominating really. He definitely slowed down quite a bit, but was still dominating Fabio. He just had a Melvin Manheouf moment and got sloppy and too over confident in his stand up for a split second and got clipped.
