The Wilder knockout on Stiverne doesn't make the AJ fight any more immediate imo. That result was always going to occur and as far as I am concerned I would keep AJ away from Wilder just for the time being, left the battle bubble up a little and let AJ go and take the Parker belt so he holds much more sway than Wilder when the time comes. Wilder is nothing to be scared of and has fought absolutely no one. This is a man who was fighting the likes of Audley Harrison, Jason Gavern and Malik Scott as recently as 2014 - complete and utter journeyman and won his title in a vacant matchup, he didn't beat a champion to win it regardless of who they were. At least AJ can say he took on a champion and took the belt from him regardless of his level and Charles Martin is a higher level than Jason Gavern et al. All that will happen is that Wilder will defend against Dominic Brezeale and then follow up with a mandatory against Andy Ruiz, bypassing Dillian Whyte because he doesn't like the risk even though he would beat him.
Joshua should fight Ustinov in March as WBA mandatory just to keep the belt, fight Parker (let him have a mandatory in Feb/March) in July at Wembley in a IBF/WBA/WBO unification and then fight Pulev in order to fulfil his mandatory status. 3 wins hopefully with 2 fairly credible names on his CV, especially Pulev's and then 3 belts rather than 2. Leave Wilder and Fury till 2019 so that it has a bigger build up, AJ has more belts and has a much better CV than either and can then really command the box seat regardless of argument.
