ix3623 is a ridiculously prolific editor of MMA/sports videos that are unmatched in their ability to waste large blocks of your time. While checking out ix’s new two-part "compilation of interesting mix martial arts facts" series today, we noticed the above tribute to sick knockouts at local shows, and it might be his most important work yet. First, a point of clarification: "amateur" here means "shot with a shitty camera." (We definitely recognized a few smaller pro leagues in the mix.) But that’s just a minor detail, because my goodness is this stuff hardcore. These are not TKO stoppages. This is nine and a half minutes of guys getting knocked dead-asleep in horrible fashion. Enjoy! We also recommend ix3623′s unsportsmanlike behavior megamix, the 30-part (!) funniest moments in MMA series, and this unrelated but compelling highlight reel.
