that's like asking who would win a fight between vince mcmahon and jay leno
Danas boxercise instructor background may help him throw basic techniques although those guys dont really throw with full power or anything. They probably dont practice defence either as its just sloppy 1-2s with the ocasional air kicks. He might be on da juice and weightlift too but hes not.a real boxer or anything. bjorn probably wins via alexander semin style bongo drums beatdown
