Does everyone agree the current LW division is pretty stacked? I'd argue it's the best division in the history of MMA, but that's certainly debatable. Even if you don't think that, you have to admit it's really, REALLY good.
Tony was won twelve, FUCKING TWELVE, fights in a row in this division. And he's done it with a style that is all action, nonstop offense, and utterly violent. He has creative striking, questionable defense but amazing durability and recovery, and ultra slick grappling. Crazy long reach and the long arms also make his chokes incredibly dangerous. The best front headlock to snapdown (#snapintuit) in MMA. Arguably the best cardio in the history of the sport. Literally everything, EVERYTHING you would pay to see in a fighter.
Take a look at the history of the UFC (throw in Pride and Strikeforce if you want) and see how many other guys you can find with 12 wins in a row. Any? Now how about 9 finishes in those 12 wins.
If he beats Khabib, he's pushing for a place on the Mt Rushmore of MMA. He'll be in that GSP, Fedor, Jones, Silva league of guys. And quite frankly, he's more exciting than any of them.
