Can Aldo/MacGregor be the most watched MMA bout in UFC history for a weight division below 170 pounds? BJ Penn was probably the biggest draw who fought below 170. I think UFC 101, which had BJ fighting Kenny Florian for the lightweight title (and Anderson Silva fighting Forrest as co-main), earned 850,000 buys. Can Aldo/MacGregor match that on the strength of McGregor's media savvy? Since UFC 101 also had Spider and Griffin, for the sake of balance, assume that one more big name will be on the card - Silva, Nick Diaz, Rousey, etc. - even if they aren't in a competitive bout against another big name.
