Guys like DC, GSP, Silva, Masvidal, McGregor, Sonnen, Holloway, Diaz, Edgar, Penn, etc are real martial artists that don't give a shit about weight. Infact. The term "Pound for pound" was coined for fighters in boxing that were not afraid to fight at multiple weight classes. They were the true P4P greats. This is why Jon Roid Jones will always be a coward in the eyes of true fans of fighting.
