Masvidal is the bigger fight and a winnable one for Conor. He would make more money and get more credit for beating Masvidal.
Getting another title shot he needs to beat one of the top contenders in the division and Gaethje is an obvious choice considering he already beat Poirier.I don't think he is ducking Justin, I think he just wants the belt back as quickly as possible. If Justin had the belt, I'm sure he would be after him
