Even though this fight is now off, lazy analysis like this can't go unchecked
That's the problem here, the rankings really do reflect the ability....that's why its relevant to bring them up. Namajunas absolutely looks like a brown belt in the cage and Van Zant looks like a low level blue at best.
Honestly can't tell if you're trolling, but...
Her "domination" over Herrig involved Van Zant going for the WMMA throw off the bat, getting her back taken, mounted and nearly armbarred within 90 seconds of the 1st. The only time she got the upper hand in the grappling was when Herrig gassed out after a round.
Her "domination" over Curran had her get hit with the WMMA throw a minute in and put on her back the rest of the round. Curran also hit her with the WMMA throw and a trip again in round 2.
Her "domination" over Chambers included a couple failed attempts at the WMMA throw before kneeing her in the eye and choking her when she fell down. Same thing with Curran above except strikes to finish after the knee.
Mind you those last 2 have a combined record of 9-8.
If you watch PVZ's fights you will see she is a bad grappler who makes big mistakes while scrambling wildly.
Unless Eye got rocked with a big shot, I doubt it. Plus do you really expect a natural 125er to be taking down fighters like McMann, Pena, and Tate who are all shredded at 135 and primarily grapplers? Not being able to take down fighters like that doesn't mean you can't take down a strawweight in PVZ who routinely goes down to a simple head and arm throw and then gets stuck there.
See above. It matters more often than not (ie: on average you're not going to catch blue belt-level grapplers subbing brown belts). It's also easier to just reference belts in this situation because they match up pretty well with the fighters actual ability unlike someone like Jon Jones who giggles about having a white belt but has been grappling for over 15 years and was a D1-quality wrestler.
Namajunas is great and showed how bad the skill gap is between her and PVZ, but we don't know much about Waterson at 115 aside from a can in Magana and a PVZ that fell into the same old trap as usual.
Bottom line: there is nothing logical on paper to lead someone to believe PVZ has a grappling advantage over a larger opponent with more experience. If some stupid shit happened and Eye got subbed with an imanari roll to darce then so be it, but prefight analysis doesn't make sense to give the edge to PVZ in the grappling.
But yeah its off so who cares
