Have either of you guys ever rolled before?
If a pure wrestler decides to use his wrestling against a very good Judoka or BJJ practitioner, that wrestler is going to get submitted because they don't have the correct defense for those submissions.
It happened at my friend's gym all the time when he was doing BJJ there. A lot of pure wrestlers would go in and of course, they would use their wrestling by they got easily handled by the BJJ students because the wrestler doesn't know how to defend those submissions.
You can say that any wrestler above 135 handles her, but if they are just a pure wrestler and don't know how to defend the submissions a Judo or BJJ practitioner has, then that wrestler is going to get submitted.
In order to be successful in MMA, you have to learn submission defense. You have to learn BJJ/Judo, etc. You can't just rely on your wrestling. You can be an amazing wrestler but if you don't have any knowledge about submissions in BJJ/Judo, you're going to get submitted very easily.
That friend of mine, he rolled with tons of pure wrestlers and submitted them very easily. Most of those wrestlers never came back the next day, either.
The only way the wrestler wins is usually if the BJJ/Judoka sucks or the wrestler has experience in defending those kind of submissions/is used to having submissions and sweeps from that style (BJJ/Judo) thrown at them. If they're just purely using their wrestling and don't have the submission defense, they will not win the match, they will get submitted or they will get swept.
Now, if a Judoka or BJJ practitioner went in and tried to wrestle, they likely will not win. If they have to go in and use wrestling instead of their actual base, they will lose. But if you put a pure wrestler against a BJJ or Judoka, the BJJ or Judoka is going to submit them because that wrestler doesn't know how to defend the submissions or the sweeps. If you do BJJ/Judo practitioner vs. pure wrestler, the BJJ/Judo practitioner wins almost every time.
Size has nothing to do with it. A good BJJ or Judo practitioner will submit the wrestler. Royce Gracie proved this already, that BJJ is superior to wrestling if it's pure BJJ (or Judo) vs. pure wrestling. Now wrestling with some BJJ or Judo experience (submission and sweep defense) vs. pure BJJ or Judo, the wrestler will likely win. But, if they don't have that knowledge, they will get submitted or swept quite easily because they don't know anything about that style at all. They aren't used to having armbars, triangles, etc, thrown at them. The BJJ/Judo practitioner > pure wrestler.
EDIT: Don't talk about how the wrestler would just slam them on their head, because it's really not that easy. There are ways to defend being slammed in BJJ and Judo. Look at how Forrest Griffin defended being slammed by Rampage Jackson when he put him a triangle. BJJ/Judo > pure wrestling. Wrestling with BJJ/Judo submission and sweep experience (MMA mix) > pure BJJ or Judo, unless that BJJ/Judo fighter is fucking amazing, like Werdum or Jacare or something.
