Conor is quite simply the biggest star, largest personality, and the most exciting fighter in the UFC. All of his fights are must watch. He is an incredible talent that is fighting a taller, heavier, and more durable man who already beat him. And despite Conor being the most exciting fighter in the UFC, Nate actually has the most post fight bonuses in UFC only history. I'm more excited for this than UFC 200 (to be fair, I'd have been more excited for Cormier vs Jones), and if you guys have any interest in MMA at all, this is one you should watch.
I think Conor should be a larger favorite than he is. He completely dominated the first ~7.5 minutes of a fight where he moved up 2 weight classes on short notice. I understand Nate took the fight on shorter notice, but Nate always trains, has cardio for days, and his style is less reliant on having a proper training camp. I think Conor is more cautious, adds more leg kicks (Nate's kryptonite), doesn't gas out this time, and picks him apart en route to a TKO/KO win.
And unlike boxing, this is not a 1 fight event. Anthony Johnson vs Glover Teixeira will likely be lopsided in favor of Johnson, but the winner will fight Cormier for the title. And Donald Cerrone is an exciting fan favorite that, when including his WEC fights, has more of the night (not to be confused with The Night Of) awards than any fighter in UFC/WEC history (Nate is 2nd overall when including WEC).
Conclusion: don't make other plans Saturday night.
