The most hyped fight of recent history got scrubbed, and yet the current headliner for UFC 189 is nearly as compelling for stylistic reasons, and much riskier for the UFC as a promotion. Jose Aldo was going to be a striking test for streaking Irish phenom Conor McGregor, but the last-minute shuffle changes things altogether, and accelerates the wrestling matchup non-Irish fans have been begging for against Chad Mendes. What happens in this fight will significantly affect the European MMA market one way or the other, could bring Team Alpha Male a second belt, and will also determine Aldo's next opponent. There's a lot at stake in that main event, and there will be a lot of people watching.
