WATCH: Anthony Johnson proves just how heavy his heavy, heavy hands are

He's the pound-for-pound hardest hitter in MMA and there'll be no debate about it.

If any part of Anthony Johnson's fist hits your head, you will quickly find yourself dreaming of a time when the former welterweight was missing weight so that, at least, you'd have some bit of purse compensation to look forward to. But Johnson's a light heavyweight now. And he's one of the best in the world. His main event match-up with Ryan Bader at UFC on Fox 18 was essentially an unofficial title eliminator for a shot at the winner of the Daniel Cormier vs. Jon Jones rematch. And 'Rumble' decided early on to take his fate out of the hands of the judges by recording his fifteenth career knockout. It's not often that ground-and-pound from back mount results in a genuine consciousness-robbing knockout but Johnson's victory was definitely more than a TKO.

Bader's legs went limp under the weighty, undefended strikes from 'Rumble' which forced referee Keith Peterson to jump in and call a stop to proceedings. He is a scary, scary man. https://twitter.com/Flyinjudoka/status/693628066178924544 https://twitter.com/EliasTheodorou/status/693627916501000192 https://twitter.com/ChrisCamozzi/status/693628198169411585 https://twitter.com/Jon_Anik/status/693628219296235520 https://twitter.com/EddieWineland/status/693628365350293504 https://twitter.com/Ealvarezfight/status/693628526369599488 https://twitter.com/TheRock/status/693629552438988801
