The criticism of Jones is absurd
One of the first things I learnt in muay thai/boxing defense was the long/extended guard, the exact outstretched lead hand, rear hand on forehead style that JJ uses. Excellent for keeping shorter opponents at distance - the only difference is using open gloves, it leaves an opponent who is rushing in in a dangerous situation - of his own doing.
I'm not going to leave my lead leg out the entire fight for Shogun, Alves or Aldo to chop away at
I'm not going to stand in the pocket with Lawler or Hendricks
I'm sure as hell not going to be flat footed, hands up high and standing square on to Sonnen or Rashad.
Don't want to get eye poked by Jones? find a way to get in the pocket, put him on his back or put him against the fence and grind it out and don't give the lanky fuck space to use the limbs to advantage.
