How do you walk in a room with an ego that big? LOL You say you're 160lbs that's not much bigger than MM walking around weight, maybe 20-25 lbs. For sure his techniques, cardio, speed and yes Power would kick your ass.
Obviously you've never rolled with any professional athletes. I'm 220lbs and 6'3 ,wrestled in school, did amateur boxing . Once got to roll with Frankie Edgar, who's a 145 er. That's a way bigger difference than you and MM. He kicked my ass. No matter how tough you think you are a UFC Champion is on another completely different level than you. Especially one who's considered one of the greatest EVER!
Nothing to be ashamed of , it's called years and years of experience, not to mention he does it for a living.
Seriously if ya think your that good you should be trying out for TUF. You could be the next TUF champ.. Hell you should be able to beat Cruz and Cody too.
