Who would win this fight? I know barboza vs gaetje would be an awesome fight too but I really think gaetje can finish lee. I am sure lot of sherdog would love to see the beast I.e JG finish lee like he finished big boy Vick. JG has the advantage in terms of cardio, heart, toughness/durability, power and possibly standup too. Kevin Lee has better wrestling credentials but JG is no slouch there either. Lee has better grappling, strength, speed and ground game. he has an average chin and poor cardio which always lets him down. I really believe Justin would get it done in the 4th or 5th.
