Well, Zuluzinho is set to fight in Pride 30, and I read that he has a BJJ purple belt. I was just curious as to how they evaluate his skills - I mean a knee on belly from this guy would most probably hospitalise most people, and just having a beast like that in your guard must be horrible. Also, if there's any chance whatsoever to muscle out of a submission, this guy probably does so in his sleep. I guess he isn't much of a quick mover while on his back (but who could ever put him on his back?), though, and I guess his transitions can't be much to write home about. All in all, I guess he can tap out a lot of the BJJ black belts out there by smothering/overpowering them, but that says little about his skills. So, on what grounds do huge guys like him get their belts?
