I think that it is important for young heavyweights to model themselves after the Ali or Holmes type boxers because that skill level is missing from todays heavyweight. The jab wins fights, and a lot of these guys dont realize that. Now they all rely on power and even the top heavyweights are plodders. Young heavies should study Ali-Williams or Holmes-Shavers and emulate their movement and jab. Obviously not every guy has the build or ability to to fight certain styles, but if they do they should learn from former great fighters.
