Belfort has a Gracie Jiu-jitsu background, so in principle you might expect him to rely on a lot of fancy submissions, but as you can see, he's winning these things by slugging. It's very effective. Most of his matches last about ten seconds.
The geometry of his style is different from Wing Tzun's, Egemen notes, but the principle is the same: Combinations, which require you to vary your angle, disrupt your balance, especially if you're pursuing someone. "I'm not saying combinations are wrong," says Egemen. "Nicely applied combinations, done by people who know how to throw them, create minimal disruption of balance. But they do still disrupt balance."
Egemen stresses again, though, that "highlight videos are dumb."
