I think people are reacting this way because he's stating these facts like he came up with something brilliant, and then claims if you follow this formula you will defeat the grappler.
Saying things like Strikers need to try and get up completely ignores the fact that the grappler is keeping them down. I mean, seriously, how can you make this kind of comment and expect it to be taken seriously?
The reason people are on his case about not fighting is because if you put him on the ground, and you put Randy Couture on top of him, he will end up laying there exhausted after 2 minutes and will NEVER be able to get up.
He would likely get punched in the face from that position, then give up his back to avoid the punishment and get rear naked choked. I think that is the more realistic formula.
