Watch the whole thing. Look how beat up Stipe is. Contrary to popular belief, that was DEFINITELY not an easy fight for him. He got rocked more than a few times but his level headedness, very high fight IQ and calm under pressure allowed him to impose his gameplan anyway. I think it was in the first round when he pushed Ngannou back against the cage and Ngannou caught him with this almost arm punch hook going backwards that completely buckled him but he brilliant got the takedown anyway. I was very surprised no one in the booth commentated on that.
I wonder if him being a fireman is how he can stay so calm under such pressure.
Anyway, anyone that thinks that Francis is a joke now and wont have a chance against the other top guys and so forth are delusional. Even as he is now, he has a good chance against everyone. If he improved his wrestling and his game off his back (getting up) and take his opponents seriously and measure (like he did with Overeem) instead of just throwing bombs then he might even beat Stipe I think.
