7. Ricardo Mayorga
This dude was off his rocker. Mayorga hyped many a fight by talking a bunch of smack and getting his opponents heated during press conferences. In his native Spanish, Ricardo would insult guys by calling them homophobic slurs and blowing cigarette smoke in their faces. He would also deliberately take shots to the head and act as if they weren't hurting him. That plan backfired when he tried it versus Felix Trinidad. Mayorga took three hooks to the jaw but he wasn't planning on his legs turning to noodles on the last one. If only he could back up his talk in the ring, he would've been one of the greats. Check out the awesome highlight reel of hall of fame trash talk. He's one of the best.
