Most people would agree that Anderson Silva is one of if not the best mixed martial artists of all time. That's not what we're here to talk about . I wrote this fanpost to get some feedback on your thoughts about dominant champions wasting the primes of their career's on meaningless title defenses . After a fighter has cleaned out his division he should be expected to move up in weight . In boxing this is common practice . Sugar Ray Leonard came out of retirement and defeated Hagler for the middleweight title . Roberto Duran is widely considered the greatest lightweight of all time although he wasn't as dominant when he moved up he did it because he had to to be challenged . Now back to Anderson Silva it's my opinion he should have moved up as soon as it became clear that he was head and shoulders above all of his fellow middleweights. All can be forgiven though if he mans up and demands to face Jon Bones Jones . We as fans should be demanding this fight takes place . A win over Jones would further solidify SIlva as the best to have ever set foot in the octagon , all the greats take on the toughest challenges available and Anderson should too .
