He might actually be the most talented genetically.
- Fast and agile as fuck for his size
- Unreal power even at short range
- Ungodly strong
- Has a chin (took some deadly shots from Stipe)
- Has heart (never quit against Stipe)
And the most underrated aspect:
- He LIKES it when guys try to wrestle him
Seriously, rewatch the Lewis fight and notice how Ngannou couldn't much of anything because Lewis didn't approach him. It was only when Ngannou closed the distance on his own in the end that he felt comfortable throwing. When guys wrestle him, they close the distance for him, making it comfortable for him to throw since he's a counter striker (except in the Stipe fight where he fought like a crazy idiot).
If Lewis rematches Ngannou and doesn't charge at Ngannou, Lewis would win again. Weirdly enough, doing nothing is an effective strategy against him possibly.
