Ok here's your chance to say I'm on crack.
I think that a boxer like Chris Byrd today is twice the master boxer of Ali in his prime. Larry Donald is a very good boxer and probably Ali's equal in overall physical ability,speed,jab,ring generalship etc. The thing of course that sets individuals apart is character,which some guys,like McCline are lacking in. Ruiz is a frustrating fighter whose style i personally hate but has proven himself against the top guys for a long time,much to my dismay. Guys like Joe Frazier if he fought todays fighters wouldn't make the top 20.
Please keep a look out for my
