You're crazy if you think 520k buy rate is a bad number.
He will do a better than average number on TV and would probably add decent numbers if he was in the co main event as well.
Dude, that was back when he fought Jon Jones for the title. And that was outdrawn by five other events that year. And it was over 3yrs ago. He's not a draw anymore man. And based on his current physical abilities that's not going to change.
If current physical abilities matter , explain to me why Jones and Rampage did much better than Glover - Jones and Gus - Jones by a considerable difference .
Both had much better recent records than Rampage where he came off a decision against Hamil and Machida (where he was lucky to win).
