I mean really Jones's style and defense was one big mistake or flaw. All of what made it work was the price he made you pay trying to capitalize, if at all possible in first place. What he had you can't train or relate to many different fighters. I'm the furthest thing from a Roy defender but while Mayweather is a defense wiz he, I believe, is more familiar to war-game against and set plan of attack for. Floyd has mad defense knowledge and reverse gear but between the two he was the far more 'common' style of the two as far as boxing 101. What really makes it for me is the price guys payed trying to penetrate each defense.
