If Fury continues fighting...he can make a long reign

[JakeTheBoxer]

There is nobody around, but Joshua. Other guys are not even a real threat.

If Fury continues his career, he can make about 7 years long reign, but having all the belts. Then would probably some DDD alike guy beat 39 old Fury.

Fury can actually probably defend his titles into his 40s, he has a style that rages well, he just needs to be more economical with movement down the road when his stamina takes a hit.

I agree though, it will he interestingly see challengers try and dethrone the king of boxing.
