Clinching isn't illegal. Fans think it is, but its not. Clinching is part of the sport and basically happens in every single fight there has ever been and will be.
er.... Hitting on. a break is illegal. One of the worst fouls in boxing. You can't excuse a blatant foul because you like one fighter more than the other.
Depends on what made him go down. Was Garcia leaning on him or pushing him down? If he was, then a KD doesn't count, even if he was hurt before that.
Fact is, both guys were fouling all night long, you just seemed to only care about one of them.
