If he wanted a more direct path to AJ or Wilder, he could have fought Pulev to become the IBF mandatory or Ortiz to become Wilder's WBC mandatory. Hearn must have something up his sleeve politically with this fight or it doesn't make much sense in that context.
I can't say I've been impressed by Parker in his last few fights tbh, I don't think he did anything v AJ to justify being on box office again. He has a decent skill set but doesn't hit hard enough at elite level. Whyte is improving technically but still telegraphs most of his power shots and is much slower than Parker in most aspects.
I am in the minority it seems but this fight doesn't really excite me much. I think their styles may well clash and produce a bit of a messy, boring fight. I would much rather have seen Whyte v Ortiz, Pulev or even Breazeale if the Alabama windmill decides the latter is too scary for him.
I can only echo what others have said too, there must be an immense undercard incoming or this is Matchroom's worst PPV since Cleverly Bellew 2 imo.
