Gaye? What are you 12 year old? Regarding Haye vs Joshua, I believe Joshua has elevated himself to the level where Louis adequately put as "Everyone's got a plan until they get hit". It'd take someone with size and a great chin to resist his power. There are few people in boxing who fits this description and Haye is not one of them.
Would be an awesome matchup and a great way for haye to quickly reestablish his relevance quickly, given how popular AJ is getting.
Haye would never get in the ring. Sure he might sign the contract, but he'd pull out with an injury. It's vintage Haye.
