Like I said, this is the age where fighters who used to be good basically get old in the ring. Although he showed his handspeed and foot movement, he's just no longer the same.
Next is Floyd Mayweather Jr, he will be 36 next year. Let's see if any young fighter out there is good enough to take advantage of Mayweather slowing down. Though Floyd would never fight off balance like Guzman so who ever beats him will have to do it purely on the scorecards or by forcing a stoppage by getting him hurt while he's still standing. They will not knock Floyd down like that, all of balance.
Guzman is past it, but he did show that he's not shot, just old. I knew Khabib was the perfect fighter to do this.
