If any of those names trained at your gym you would be like ZOMFG I train with UFC fighter ZOMG balls balls gag. But because they're on free tv they are shit and not worthy of watching. So don't watch it. See if anyone cares. Virtually all of them have multiple UFC fights over years. They are names. Are they huge names? No, but they are talented fighters and you will see skillful martial arts and you will likely see exciting fights. If that interests you, watch.
