Somebody messed with the wrong teenager.
Veteran MMA fighter-turned coach Alex Enlund posted video of one of his students, Alex Williams, involved in an altercation on the street in which Williams, a multiple-time BJJ world champion, deals with an attacker. Watch that video below.
We see the teenager defending himself with the full scope of his training, responding to a knee from his attacker with a swift double leg takedown. Williams clearly could have done more more to his attacker, as he was standing over him threatening to throw punches. However, Williams backs away, hoping his attacker would do the same.
Enlund posted a follow up to the video, complete with a quote from Williams.
