I think Max would kock him the fuck out. Seriously. And Pettis is way too long, and way too durable for Dom. Dom wouldn't be able to scratch Pettis' durable ass.
Also, if Mendes looks anything like he did before, he would rape Dom. And a fighter many forget, Dennis Bermudez would pummel him.
I'm serious, these guys are too big, and robust for frail, Dom. Dominick can't generate the type of speed and power that FWs can, because he doesn't have the weight behind him, or under his shots to generate the type of velocity these thick ass small guys can.
These guys are small, quick, powerful, and thick. Dom is small and quick. He doesn't have the physical densness to be powerful and explosive like the FW fighters.
