I would say the Browne v Barnett elbpws to the temple are as likely/more likely to cause major concussive damage and a death in the sport than soccer kicks. Soccer kicks rarely land flush, and if one does land flush that is usually it. Look at the first fight in the highlight video, that guy shooting for the double goes in and out of consciousness and takes like 10 of those elbows to the temple. I don't like those. Soccer kicks end fights quick, and you only rarely get one that lands as clean as the one that nailed Huerta.
