Compare a guy who hasn't even been fighting 3 full years to guys who have been fighting for about 8 years.If you're gonna compare him to Wilder or Fury, also include in there that Joshua has easily the worst resume of the 3.
He hasn't faced a B-Level Heavyweight yet...Martin was a bum who got lucky. One of the worst "legit" Champions I have ever witnessed in Boxing history
3 years into Wilder's career he was still fighting club fighters, part-timers and palookas...shyt he is still fighting dudes who have full-time jobs while he is a world champ.
And Fury didn't step up his own comp until deep into his 3rd year when he fought Chisora.
Neither guy was fighting top competition at the same point in their careers as Joshua is.
