29. It is tough to get a double leg on a tall guy like Jon Jones or Gustafonson if they sprawl well and play defense. Roid muscle ala Coleman, Vitor, Randleman, Mark Kerr, Overeem etc. can gas a man quickly if they do not get the quick knockout in the first round. The muscle takes tons of blood and oxygen, so often the taller fighter has more stamina and defense the first round to gas the more explosive guy and tie him up later.
