It's a big money fight, and Dana is hedging his bets. If Conor loses to Aldo, Conor can main event against Faber in a "grudge match." If Conor wins, Faber will be 1 win away from a title shot. Faber should fight on the same card as Aldo vs McGregor. If Faber wins on that card and McGregor wins, Faber can challenge McGregor afterwards. It's a fight that will draw a lot of interest because both guys have large fanbases. Edgar will then say McGregor is ducking him, he'll be waiting in the wings, and that fight will build hype and interest. Conor will likely beat Faber and by the time he does the calls for Edgar vs Conor will be at a fever pitch.
