Nate Diaz took the fight with Conor McGregor on roughly two weeks notice. Everyone knows Diaz is a tough dude, but I don't think anyone thought he would beat McGregor.
But Diaz did, he submitted McGregor with a choke. This is nothing new for fighters who get too mouthy and too cocky. It eventually catches up with them.
McGregor might want to think his plans to hold belts in three weight classes. It's not that easy.
