Referee Leon Roberts is quietly building a reputation as one of the best MMA refs in England. Just go to 6:25 of the video above to see why. When Roberts was reffing an amateur Lightweight bout at Fight UK: Last Man Standing on April 26, Nathias Frederick dropped Ahmad Aswad with a punch and didn't want to stop.
Roberts promptly took Frederick's back, got both hooks in, rolled Frederick and threatened with a rear naked choke.
Middle Easy quoted the following from the email tip that alerted them to the story: "Leon Roberts is the nicest guy I've ever met. I travel with him when we're on UFC duty and he's arguably the most gentle giant you will ever speak to.
However, he knows how to get it done. He never has to say it, it's just a given."
Can't argue with that. Speak softly and carry solid technique like Ref. Roberts and you'll be just fine.
