Well apart from those things, I think that this time Crawford is much more hungry for victory and this is something that when a boxer is clear about it he would do anything to achieve it, to see Crawford how everything has gone, in his training and everything could I clearly said that Crawford, even if his body fails him, will not give up,
I think being
"hungry" is not the appropriate term. It's just that Crawford is the one who clearly chases the legacy over anybody that's why he is aiming to defeat those other title holders. It's not being hungry but part of building a legacy and this fight against Spence will now seal who's the current best Welterweight. It's a must-win for both fighters before considering moving up to face challenges there.
On the other hand, it's not that Spence is not aiming for a win and that was insane to think. He is holding 3 titles just for nothing. He's also a real deal. If Crawford is doing his best on training as you mentioned, the same goes for Spence too.
Won't be an easy fight for both and I'm expecting an intense exchange of blows once they finally faced each other.
