I feel you. Firstly, you were entirely right that we won't see Crawford fighting any of the young lions at 47 as long as he's under the Arum banner let alone Spence. Secondly, there has been some hypocrisy but I think it was always asinine for people to say Kell was "done" after GGG. He fought a middleweight and lost. He didn't even get KO'd. They stopped the fight and Im not sure he couldn't have continued. I think Kell has plenty left. I wanna see him and Khan fight finally
Sadly, we've heard all of those statements and people tend to get amnesia when another fighter puts on a great performance. You know how I get when boxing fans clamor for a fight and doesn't support it (i.e. both Kovalev/Ward fights).
What if they miraculously made a Spence vs Crawford fight and put it on PPV? Those numbers would be atrocious, if I had to guess. Boxing fans beg for fights and won't support them if a price tag is attached to it. Crawford will fight Arum-made fighters at 140 or 147, or rot on the shelf when contract disputes arise. Arum did mention him fighting the winner of Pac/Horn though. *shrugs*
As for the hypocrisy about Kell Brook, it was horrible. Fans wouldn't stop bringing up their concern about cutting down to WW and his the condition of his eye, but as soon as Spence beat him, they called him a quitter and so on. So, why should Spence get so much credit for beating a compromised "quitter"? If I had to make a bold statement, I'd say that Brook was ripe for the picking. I have much respect for Spence, so I won't stick by that statement.
If Kell fights Khan, they need to do it at 154, but I can see Khan trying to flash his non-existent negotiating power and demand that it takes place at 150 lbs...only because I know he can't stand Brook, lol. So, Brook will probably be 3 lbs north of a weight that he shouldn't be fighting at, and he'll deprived of 4 lbs that he needs to safely make weight. I'm not even sure Khan has that much drawing power nowadays for that type of fight.
