Its always been strange with how Eubank jr seems to go for smaller guys than himself Benn jr, Kell Brook straight after the Khan win but when the opportunity is there for him to test himself against the top men at his weight or near to it he's not so interested anymore (GGG, Canelo). I think its much more about the easier pound notes then testing himself or legacy.
One thing is for sure Sky or whoever has the rights for the fight will do plenty of build up with Nigel & Chris snr going at it which will be entertaining.
