I think boxing it self as a sport is loosing out to the newer, much more popular, sport of mixed martial arts. The argument of which is better of the two is a very touchy subject for both sides but its clear that MMA has captured the minds of the younger generation. Personally I find MMA much more exciting to watch because of its many dimensions, but at the same time I still appreciate the art behind boxing. As far as the heavyweight division of boxing is concerned, I believe the main reason for the lack appeal is the lack of charisma in it champions and lack of worthy opponents. If you look at champions of past such as Ali, Tyson, Jack Johnson, Marciano to mention a few they all had their own brand of charisma that attracted attention to the sport. Tyson was a nut-case that had the talent to match, Ali needs no explanation, Foreman was just so menacing and dominant and many more who all brought attention to the sport, whether good or bad, and were blessed with amazing talent. These fighters faced worthy opponents at every stage in their careers which reaffirmed their greatness. In his career Ali faced Sonny Liston, Joe Frazier, George Foreman and many other great fighters. I believe this combination of charisma and talent is what made the heavyweight division the marquee division of boxing in the last century. If you look at boxing now who has that charisma to make people root for him or just plain dislike him for no reason? Beyond Mayweather ( an absolute punk, though a highly skilled punk at that) and Pacquiao (class act) its hard to think of any. The Klitschkos are great fighters no doubt but in this era they are made to seem even better because of the lack of good opponents. As good as the Klitschkos are they have boring personalities and unless you are Pacquiao just being a class act does not cut it. It works for Pacquiao because he faces worthy opponents. The way the things are going it hard to envision heavyweight boxing making a comeback. The world nowadays demands more excitement and brutality, things that heavyweight boxing once offered, but it seems heavyweight MMA is the answer to that for many. Parting question; Who would have won between Jack Johnson and Ali? or Joe Louis and Ali?
