Miller needs a decent guy on his record to demand Joshua. Povetkin/Miller/Whyte/Parker etc all need to fight each other and give the fans good fights rather than just fighting C level fighters and 'waiting their turn'. Why isn't he wanting Wilder? If he takes Wilder, and wins, he gets Joshua straight away.
You can say this about almost every division in boxing & it woyld be true! Middle weight & Welter weight come to mind. @OpinionOfACasual I cant agree more.
