Jon Jones gets the submission and I do not think Gane landed a punch?
Well he gave Jon a swift kick in the bollocks. Does that count?

I am disappointed with Jones vs Gane fight. I think I did not have enough of it. 2 minutes and it is over. This was too easy for Bones. It only showed that you can slack for years, get in the ring and win. I would say that this fight showed that Gane is way too weak against wrestling, isnt prepared, perhaps overestimated. This fight did not show that Jones is the greatest, or how some people say: "the greatest fighter of all time". If this was Ngannou in the ring, we would have seen a completely different fight.
You don't know how hard he's been training though. Being out of the ring for a while can be deceptive especially if you're sparring heavyweights multiple times a week and training hard every other day.
I do not know if the rumors are true about him injuring his hand but he did not look like the fighter he has been the last 2 years.
Well maybe he will have excuses or maybe he just got overwhelmed by a better fighter. Could even be both.
