I guess it depends whether you regard the elbow strikes, forearms, shoulder bumps and palm strikes as straight boxing or not.
I've seen a lot of straight boxing too and to my mind this has some differences from what most straight boxers do. More direct facing and use of the rear hand. Just my opinion.
Good stuff anyway, good posture and distancing, strong strikes, fast and powerful combinations. As a general rule we DO tend to quibble too much about irrelevant details on this forum.
I'd rather watch ten clips like this, than ten like the ones on the "WC revolution" thread.
