I have no doubt if I was in a full contact mma match against a pro boxer I would win 8-9 times out of ten I have sparred with pro boxers at the gym unless they have some kinda grappling back ground they have nothing coming. Even then they better have a damn good one. It takes nothing for some one with basic wrestling skills to close the distance on a boxer. A boxers normal stance tend to be horrible for a real combat. A small person makes it a lot easier to cut off the ring to. I have a little knowledge of fighting boxing to though. I think a heavy weight high school wrestler with state level skills would beat a small pro boxer 7-10 times. No one has ever came from boxing and did well in mma. Not like even mediocre wrestlers. I heavy weight boxer strong boxer presents a lot more problem
