I could see it happening. Mousasi is good but he hasn't fought anyone on Machida's level in how long? Hell, the last quality opponent he fought was King Mo and he lost. Next somewhat quality opponent he fought, it went to a draw. He hasn't impressed me in his fights with Latifi or OSP. Meanwhile, Machida stills looks as sharp as ever and has wins over top opponents and fought better competition than Mousasi.
Machida fans before Rockhold: "He's definitely at his best right now and should've been at MW his entire career. He's going to smoke Rockhold worse than Belfort."
