We will see that in the early rounds, both fighters are good at throwing haymakers, of course both fighters want to make money Ngannou will be making more than all his fights in MMA but I'm sure, Ngannou will want to extend his run in boxing if he can draw or even beat Tyson, that means more money coming in and most of all making a name for himself, but of course Tyson has everything he needs in his arsenal to contain Ngannou like what Mayweather did to Mcgregor.
The way I see it, Ngannou is only good in the early rounds, and after five rounds Tyson will take over he has all the experience to tire and dominate Ngannou and eventually knock him out or stop Ngannou.
