I didn't have the opportunity to see all the rounds in this fight, but I saw the highlights... Fury's punch must really be very deadly for it to have made a mature and experience fighter as Whyte loose balance on his feet, if the fight was allowed to continue, it would have resulted in serious complications for him. If I were other fighters, I'll try and much as possible to avoid Fury.
When it comes on being technical and being hard puncher then i dont really have doubts for Fury..Its normal for referee to make out some decisions as safe as possible for every fighter.
They wont really be that dumb on letting a fight continue if they do see there's high chance on bigger injuries if it would be pushed further.
You could really see the reach do really make out some advantage i would say but the power difference is really that noticeable.
