Mo gave a good analogy, he gave Jones credit also:
You are running a marathon/race & you start to hit your stride, than you trip & fall over a log. It's hard to get that same stride back when you get up.
It looked like the pressure was getting to Jones & he was getting backed up while eating jabs & uppercuts, then the poke happened & the momentum shifted back to Jones.
Daniel also said he got hit with a knee to the body early in the fight & everytime he ate a body strike it felt like an electric shock. He didn't have gas for the 4th & 5th though & those are the rounds that count(it's probably because of body shots, I would think DC would be in shape)
It feels like other fighters should be given 1 accidental soccer kick to the nuts per fight, especially if the going gets tough.
