people tend not to focus as much on things that are not as common or threatening. the idea that in an mma fight a primary focus in a clinch in the middle of the cage is to keep your head tucked to avoid shoulder strikes is pretty silly. there's alot going on and to think about there, and it's not just defense against shoulder strikes.
but his face didn't look great after the fight, and all reports post fight were cerrone was suspended for broken nose and mild orbital fracture. so if it wasn't broken, it wasn't just the commentary team that thought it was.
not sure what you're suggesting otherwise........
