How would prime Mike Tyson do against the current top heavyweights? (Joshua, Fury)

[Master]

So far it seems pretty unanimous. I'll join the chorus and say he beats all three of them. Wilder and AJ by knockout... Fury... depends. If Fury goes in there full-grappling mode he may last out a decision. He's already proven he can take a good punch.

I think it is proven he can lose his concentration and get hurt. Cunningham is not a big puncher.
