There are levels to this game. While I think Whyte has a discipline issue holding him back, he is levels above Miller. Whyte would most likely obliterate him with a left hook mid way. Whyte KO 6
Jarrell Miller has reportedly tested positive for another performancing-enhancing substance and Whyte has far more power than him anyway, completely overrated average fighter.
The fight would most likely be held in Saudi Arabia and the end result of would be the decimation of the Middle East due to the chemical reaction of there sweat molecules joining during a clinch.
On a serious note, I actually really like this fight. It has the makings of a classic. Miller's workrate and aggression constantly pressuring Whyte with Whyte countering, and neither have a good defence. I think Whyte's body assault, and huge left hook put Miller out around 7, but Miller overwhelming Whyte and winning in the late rounds isn't out of the question. Obviously it'll never happen, but it'd be a pretty good fight.
