Which fighters have signed for tougher fights than Joshua has at 21-0

[Prince Madison]

He has signed for/fought klitschko, pulev, Parker, takam, whyte, povetkin within his first 21 fights.
... Which heavyweights in recent years have fought comparable opposition after 21 fights and which current active fighters in any division have fought similar level of opposition in their division at this stage?

[Simurgh]

Lomachenko.

[Prince Madison]

Lomachenko.

Yep , arguably the p4p number 1

Pulev? Shyte is a bum and was green when Joshua chinned him. Klischko was retired and beat KO by bums way before, Takam? That shouldn't even count ; Parker neither - robberies. Pedvetkin is a fraud, been exposed and the fight hasn't happened.

AJ is the #1 fighter in the world and has been moved very quickly. Congratulations to him.

Just because it's understandable why he's ducking Wilder doesn't mean he isn't ducking.
