No because if Wilder beats Wlad it'll be when Wlad is a deteriorated 45yo man or something I dont expect him to fight Wlad any time soon, he'll try to milk his paper belt as much as he can first
No, because outside of their title wins, they created legacies. If Wilder beats Wlad and then does nothing after, he'll be remembered more like Rid**** Bowe. Someone who didnt fulfil his potential but on his best night would be a tough fight for anyone etc etc.
He'd be on his way. Wlad is ATG, clearly the best heavy in the world and Wilder would be such after such a victory. He'd need a lot more to get up there with those legends though.
