Lew is the most immature assistant coach that's been on the show. He makes Tiki look like Danaher.
edit: Toxic - JDS doesn't train in a gym of exclusive heavyweights. Every one of his sparring partners and friends at BlackHouse have to cut weight except Nogueira, to think he doesn't understand how it works or how it's done is silly. Nobody at BlackHouse has ever had trouble making weight.
