The thing with Lesnar was, at least back in the day, it was very clear that he did not like being hit in the face at all, or the liver for that matter.
He also did not have the highest fight IQ that I’ve ever seen.
No doubt he is extremely physically talented, but it seems like he really is much more than a yellow belt or so in terms of martial arts, and he doesn’t seem to have any experience in the submission game.
But maybe he has been training since he left, i don’t know.
I’ve always maintained that if Brock would have been with a real camp and been trained with some real trainers he would have been a the best pound for pound heavyweight.
