Cormier has also looked dominant at HW. That would be 2 weight classes Cormier has shown dominance. When you talk P4P, there isn't a better way to prove it than actually show you can be dominant in multiple division. That is why Mayweather and Pacquiao get so much praise, as well as Anderson and Hendo. So where would that put DC on the P4P list if he were to take the belt from Jon?
