Margarito's cheating: What does it really mean?

On Saturday night I found myself rooting for Margarito to be completely knocked out for a number of reasons. For one, his fans have been some of the most ignorant and loud people on here. Second, Cotto is my favorite fighter and I wanted Margs to feel pain. And third, he's a cheating bastard. But today I ask myself, what does the cheating really mean? Would Cotto have done better if Margs didn't have bricks in his gloves? Is Margs just a cheater who has always done this, or is it new? How many other fighters do this? My personal opinion is that the Cotto fight would've gone about the same, but the question is, would Cotto have been brutalized the same way? I don't know. Either way I was as happy with the result Saturday as any fight I can remember recently, and I hope Cotto destroys this fraud the second time around.
