Why don't) heavyweight question*

Why don't ngannon, stipe, and pavlovich try their luck at hw boxing? They pack a helluva punch. From UFC I mean.

 

Fundamentals, timing, and movement are way different. They often lack the proper upper body movement for boxing since they are used to avoiding head kicks, body kicks, and knees.

This is also not even counting in Dana White would never allow a fighter to go beyond their contract into another sport.

 

Add it's too late for them at least if trying against better boxers.

 

Because their crap boxers, Ngannou especially.
