The one that ducked Canelo. Wlad. And the one that didnt turn up and Joppy fought instead thats just of the top of my head
Senchenko who wasn't offered enough
Wlad who signed the contract that Haye didn't
Breahmer who was facing an EE anyway?...
No need to generalize at all. Pirog is willing to fight the best, Dzinziruk has also always wanted to fight the best. And, there is plenty others.
I wouldn't consider Wlad a duck.
For some reason it seems he really didn't have any intentions to fight Haye. But, would not consider him a duck.
Sturm is just a cherry picker if he doesn't fight Govolkin soon I would consider him a duck though.
Senchenko seems like he ducked Alvarez though I give you that. And, Braehmer leaving like that doesn't look good either.
