Words: Jiu Jitsu Style
When we first put this clip up in July 2015, the caption was a single line: Mackenzie showing off an innovative position back when she was a brown belt. That was the whole post, because the video did the talking — a young Mackenzie Dern threading her own lapel through an omoplata and turning a stalled attack into a clean sweep. Eleven years on, with Dern a multiple-time IBJJF and ADCC-era world champion turned UFC strawweight, that throwaway "innovative position" line reads less like a caption and more like an early scouting report on where the gi game was heading.
The thing worth remembering is how unusual this looked at the time. In 2015 the lapel was still being filed under "gimmick" by plenty of coaches, and the omoplata itself had a reputation as a low-percentage attack — pretty, hard to finish, easy to roll out of. Dern's clip stitched the two together and found the answer hiding in the gear: feed your own lapel around the trapped arm, and the omoplata stops being a finish you're chasing and becomes a sweep you're guaranteeing. The opponent can roll, but the lapel tether comes with them, and you ride up to the top. The Brazilian Jiu Jitsu lesson underneath it — when a submission stalls, look for what it sweeps — is exactly the kind of thing that ages well.
Why a Jiu Jitsu clip from 2015 still teaches in 2026
Re-watching it a decade on, almost nothing about the mechanics has dated. The lapel feed is still the lapel feed. The omoplata still controls the same shoulder. The principle Dern was pointing at — the gi is gripping equipment, not packaging — is now the bedrock of an entire branch of gi guard play. Mikey Musumeci runs lapel-assisted omoplatas and matrix entries in lightweight finals and finds slack the rest of us walk straight past. Tainan Dalpra threads tight low-friction lapel grips against the best gi black belts alive. The whole lapel-omoplata family of attacks that Dern was sketching in a brown-belt highlight is now standard curriculum in any serious gi room.
What's changed isn't the technique — it's the audience. In 2015 you could be a coloured belt in a good academy and never see a lapel omoplata run cleanly to a sweep. In 2026, an upper blue belt who hasn't at least drilled the basic version is the unusual one. BJJ Fanatics has multi-hour instructionals breaking down every lapel entry in detail; the major instructional apps run their own series on how to play the position and how to kill it. And the IBJJF has spent the years since quietly tightening its rules around lapel wraps — each edit a small admission that the position outgrew the boundaries the federation set when the gi was assumed to be inert kit. None of that infrastructure existed when Dern filmed this for a magazine YouTube channel as a brown belt.
What Mackenzie Dern's details still teach the rest of us
Strip the name out and the position still travels. Dern's clip isn't where you go to learn the most aggressive modern lapel lockdowns — it's where you learn how the sequence is supposed to feel. How the omoplata grip should stay patient until the lapel is fed, not muscled. How the lapel should travel under the opponent's body as a tether, not get yanked over the top as a club. How the sweep finishes by following the roll rather than fighting it. The first time a training partner rolls to escape your omoplata and finds themselves swept anyway because the lapel came along for the ride, you understand why Dern was already grinning in that 2015 footage.
That, more than the specific entry, is the part worth carrying forward. Innovation in jiu-jitsu almost never arrives as a brand new submission — it arrives as someone noticing that a familiar piece of kit has a use nobody bothered to try. A lapel was already there. An omoplata was already there. A brown belt with the curiosity to thread one through the other, and the habit of filming the result for a UK magazine, was quietly part of how the position became canon. Whether you ever live in lapel guard yourself or not, the lesson Dern was already living out in that clip is the one every honest gi player keeps coming back to: study the kit as kit, treat every grip as a possible handle, and watch the people who keep finding angles in the gear the rest of us only think of as clothes.
See you on the mats.
