They hardly rushed to this fight, Hearn originally stated he wanted Joshua's next opponent decided way back in early December. When Joshua steps in with Miller in June he will have not fought in 8 months which will be his longest period of inactivity, he was meant to fight in April, nothing about these negotiations has been rushed if anything it's been a slow drawn out process. Miller was the best option that was left after Wilder and Fury chose to fight each other than fight for a record payday vs Joshua and Whyte chose to play hard ball and squeeze Hearn after it seemed Hearn had painted himself into a corner with the commitment to the April Wembley date, which to be fair was the smart thing to do, but he over played his hand and it cost him the fight with Joshua. Fact is these guys asking for big spits vs Joshua need to realise there's always other options for Joshua. He choose Miller because Miller likely is taking much less for this fight than Whyte leaving Joshua a much bigger piece of the pie and according to Hearn giving Joshua a record payday. Now while I understand Joshua choosing money over the better fight, I can't applaud him for that, he can't keep choosing the more lucrative option over the better opposition. As for Whyte, he's still WBO mandatory so he'll likely get and even bigger offer when that comes around, so he's hardly in a bad position. Only risk he has is he loses before that happens, because he's a fighter willing to take risks unlike others who are happy to sit on their mandatory status and fight journeymen.
