I'm not exactly sure what you're looking to accomplish with this, but it's propaganda at best. If you're using MMA as an example, the missing part is the level of stand-up fighters, and a wrestling-favoritist rule-set. Even then, it's not like mediocre strikers never knocked out wrestlers. Kerr got his ass whooped on his feet more than once, Coleman got waited out and beat up by Williams and Smith before they invoked the time limits. Randleman got knocked out more than once in the first round. King Mo was knocked out. I mean, if all that shit in your first post were blanket truths, none of these KO's would have been possible. So yeah, a wrestler can defeat a striker, if they don't get slept in the process. Oh and that's medium-level strikers vs. reputable wrestlers, some on the World and Oly levels.
That's a huge point that people ignore. If we want to talk about the level of grappling in the UFC right now, we can list Olympians (Cejudo, Cormier, Hendo, Romero, Rousey, Lombard), BJJ World Champs (Jacare, Werdum, Moraes, Gonzaga, Antonio Braga Neto, Gilbert Burns), ADCC Champs (Maia, Werdum, Jacare) and D1 NCAA champs (Koscheck, Hendricks, Davis). Those aren't just good grapplers. Those are grapplers competing at the absolute highest levels of their sport. Fucking Jacare Souza is consistently ranked one of the top 3 BJJ competitors OF ALL TIME. He alone is more accomplished as a grappler than every fucking striker in the UFC combined.
Seriously, who's the highest-level striker in the UFC right now?
The reason for all this is simple: There's no money in grappling, but plenty in striking--especially at the top. A top amateur boxer in the US, for example, isn't gonna risk his potentially successful pro career to make less money as an MMA fighter. What about the best kickboxers? Well, look at Holzken, Spong and De Bonte. They're all taking boxing fights.
