It would probably be a good competitive roll, I would give you the upper hand given such a size advantage.
That's kind of a complicated comparison because it's mixing a female grappler with no striking skills against a dude who has a specific skill set that can counter the grappler - particularly in this day and age where many BJJ competitors don't have the ability to get it to the ground against an unwilling opponent (either with an aggressive guard pull to sweep position or leg entanglement entry game; or with takedowns...sitting down doesn't work in a fight and jumping guard often gets you hurt). Even comparing a female grappler to a male grappler in a street fight is messy, because when there isn't training in something, size and strength dominates - and a female BJJ player who has no training in striking and minimal in wrestling might have some trouble against the male who also has no training but has the physical advantage.
I think it would be far cleaner to compare a top level female MMA fighter, because they will be well balanced in all aspects of the game and can handle a strength disadvantage better. I think a female UFC champion would generally be able to hang with typical amateur level male MMA fighters, maybe even the bottom ranking male pro fighters of similar size in the small organizations. (generally nobody in the UFC, Bellator, One FC etc though unless it's a "freakshow" type fighter like CM punk...I think most female MMA champions that size would probably beat him) And a female MMA champion will 1000% slaughter an untrained couch potato unless he has freak genetics
Agree, but weren't we talking about girls who just have bjj?
This topic of "who would win in da streetz or mma" is complicated indeed because styles make fights.
For instance, if I could train a guy in only one area (striking arts or grappling arts) for 2 years, and after those 2 years he fights an elite female grappler who just knows striking (like Kyra, Bia Mesquita, or Dern, before she switched to mma and learned some striking) I wouldn't train him in grappling, but in striking, even if grappling usually beats striking.
As a matter of fact, unless he is a genetic freak (and he is not because we suppose we are talking about a normally sized human being), 2 years of training in grappling will never be enough to beat those girls at their own game. But if I train him in striking, he will be more than able to connect on them and ko them before they could come close to clinching him, let alone taking him down.
Striking will always be a glass ceiling for women when it comes to male vs female fights. The power difference is so huge, it doesn't even make sense. I read a study a while ago saying that women are 60% weaker than men in the upper body, and 40% in the lower body, that's how much harder guys hit than women, yet a trained woman could ko an other woman if she lands, imagine what would happen if a dude were to land on a woman...
So for a macho type of guy who wants to know there are no more than 5 women on earth who could beat him in an mma fight or in da streetz, I would recommend he learns striking lol
There is a reason why you only hear about guys getting beat up by girls in bjj, and never in striking arts, nor in wrestling, except if we are talking about HS wrestling, where many boys haven't hit puberty while girls already often are grown women (I remember when I was 12 or 13, me and buddies were wondering why we still were 5.2 and 90 pounds wet while many of the girls in our class already were fully grown 5.5 120 pound women, we wouldn't admit it but they could have kicked our ass easily lol, fortunately we all have put on 1 foot and 100 pounds since then lmfao)
