I don't really agree....
Ironically, I think most 135lbs girls would be best to avoid the ground with the larger male counterpart. In Liz's case, I'd say stick and move....If she tied up with most guys that'd give them a serious advantage. With me in particular it's where I'd be strongest, I'd know that, I probably have poor striking skills compared to them and they should exploit that.
If a trained 135lbs female went out and fought "most men" on the ground I suspect It'd look something like Mir / Lesnar 2, a very anti climatic and awkward beating.
I don't think most people have an understanding of training or even fighting, the first thing you learn in the gym is to respect every guy that comes through your door, and yes, even females. Even your average, untrained, not in the best shape Joe can come in and if he hits you in the right spot you're taking a nap. Training is amazing, yes, but it doesn't provide the entire framework for the killer skill set. Many men have it naturally, and many guys can go into a gym and dominate someone who's far beyond them in training due to simply having the superior physical genetics.
If I was untrained, never worked in gyms and had no sparring experience perhaps I'd be more inclined to agree that Liz would in fact go out and kill most men on earth 1v1, but, I just don't buy it. I've seen many relatively untrained guys who would have to go easy on a girl in practice even if she'd been there for years ahead of them, I've seen it first hand and it's just how it is. Men are naturally stronger, bigger and are far more aggressive in suite.
