Armstrong beats Marquez. At 135 Armstrong was still young, if not at his peak then almost there, while, at that weight, Marquez had slowed a bit. It would be a good fight, but Armstrong knows how to bring pressure and maintain it. A guy like Diaz just comes and throws punches, but because he gets his weight up on his left foot, he doesn't punch too hard and he eats uppercuts. Armstrong didn't do it that way. Wide UD with late round domination by Armstrong, or he stops Marquez late.
Ike Williams was a really really good fighter and he could do it all. Box real good, every punch in the book, fight inside or outside. He's going to beat Mayweather.
Mosley was something at LW; he fought like an old time fighter. By that I mean, he didn't slip and then punch, or bob/weave, then punch. He punched on the move, and you don't see that any more. He was fast and hit hard, and it wouldn't suprise me if he stopped Whitaker.
Benny Leonard vs Duran should probably be the finals (unless Armstrong or Williams beat Duran). Leonard hit hard, but not as hard as Duran, and he was faster, better defensively, and he was smarter than Duran, especially Duran at LW. (Not that Duran was stupid, he just got smarter later) Leonard could hold his own inside, too. After all, he was 5'5", so it isn't like he was an outside fighter. He moved back and forth realk well.
