This fight looks a bit like a Khan/Brook move from Bellew - take a fight he can get a good payday out of that doesn't damage his standing in his own weight-class.
Difference is Canelo and GGG weren't ducking anyone in their own weight-class in taking those fights (except Canelo maybe ducked GGG given he's the supposed lineal MW champion and gave up the belt rather than defend it against GGG).
Haye has lots of options in the heavyweight class - a lot of them would love to take him on at wembley, but he's not taking a HW option, he's taking a cruiserweight.
