It has been an amazing ride to watch him here locally in Houston to where he is now within the top 10 of HW in the world.
With that said, we can all see his major weakness. It isn't his gas tank, while that it one of them, it isnt his major one. It is his overall technique, or lack there of. Derrick has consistently been a fighter willing to eat bad shots in the search of a strike, or series of strikes, to end the match.
Travis Browne exploited Derrick's belly with kicks. I would be willing to bet that anyone else that faces Derrick down the line will continue to go for his gut until he proves otherwise that it is a bad idea to do so.
I honestly want to see Lewis vs Hunto or Lewis vs Ngannou
