The story

B.J. Penn earned his jiu-jitsu black belt in about three years and in 2000 became the first non-Brazilian to win the black-belt division at the World Jiu-Jitsu Championship. He brought that grappling into MMA along with fast hands, elusive head movement and strong takedown defense. In 2004 he moved up to welterweight and choked out Matt Hughes in the first round to win the UFC title, but was stripped after signing with another promotion. Back at lightweight he beat Joe Stevenson for the title in 2008, becoming the second fighter to win UFC titles in two weight classes, and defended it three times before Frankie Edgar won a close decision in 2010. He fought everywhere from featherweight to openweight, last competed in 2019, and entered the UFC Hall of Fame in 2015.

Steal this

When an opponent turns or scrambles, take the back, sink the hooks and finish with the rear-naked choke, the way he won the welterweight title from Matt Hughes. Grappling students can drill back takes from scrambles, and MMA students can pair them with head-movement boxing.
