It was reported before that Manny is asking too much against Crawford, but if he wins here, Bob Arum might go for that big asking because he knows Manny would attract big fights and fans are already allowed to watch in the arena.
It makes sense that Manny Pacquiao is asking a big amount of winnings against Crawford because even with the reputation of this boxer, the distance between him and Manny is also too much. Crawford would have a big paycheck just for accepting the fight. Manny is the one who will attract the most viewers and even sold out all tickets and PPVs.
It's also the same with the fight with Errol Spence as Manny will take the most percentage of revenues which it should be. Manny is close to retirement and he's just picking a worthy fight alongside big paychecks.
