Yes, the Francis who fought Lewis is the same guy who defended Miocic's takedowns, was landing leg kicks, reversed his TD on a switch and knocked him out in their second fight. Exact same fighter. No question. What's next, you're going to tell us that Francis' leg injury wasn't real against Gane?
Jones should be favored against Francis in a theoretical fight considering his history, but we know so little about Jones at Heavyweight - movement and cardio with added weight; chin against bigger guys; defense and durability as he's gotten older - while also being aware that Francis has true kill shot power that it isn't isn't crazy to think that Ngannou knocks him out either.
