Dana was pointing at the success of 239 having something to do with Amanda and Jon's starpower.
Im willing to bet more people bought it because it offered 5 quality fights. The first 2 fights could have easily headlined any ESPN card and the last 3 could have all headlined a PPV if needed. The UFC has more than enough fighters to make each card have Atleast 4 quality fights with names. I don't think people want to pay for a good main event and 3 or 4 fights that should be on the prelim.
Ill take a card with 4 or 5 good fights with popular fighters over a main event with 1 star and 3 or 4 prelim level fights anyday.
