I know that. But who is Rory McDonald to say where a fight should be.
He probably doesn't have a say, like it was mentioned above, GSP is the only real Canadian fighter out there that is headlining worthy so why not build up his predecessor? If Rory thinks it'll help him fighting in Canada again so be it.
Carlos bashed his brains in once before in Canada, I'm sure he won't mind doing it again, it's what he does.
