Fight strategy I believe is to get this man into the deepest waters you can; how will he react when lying on the bottom for a long time, how will he react in a 5 round fight as there is a lot of muscle mass there that needs lots of oxygen to drive forward, how will he chase a moving target, how does a 3rd or 4th round Ngannou behave as opposed to one who dispatches foes in the first 2 minutes or so. No question of his power as that is documented but the greatest fighters will take you out of your comfort zone quickly with an outstanding game plan. And they all can be knocked out Mr. Foreman said to Muhammad Ali said the "Rumble in the JUNGLE".
