I think JBJ beats every active HW on the roster easily. I also think Lewis is a harder fight for him than Ngannou

Why would Lewis be harder ?

JBJ is on a visible decline and will have a tough time in his next fight much less rancis

Lewis is a hard fight for anybody. I think his striking is scarier than ngannou.

At LHW it seems like it. It looks like he put on mass in a good way for HW and HW is not the strongest division, while LHW is an extremely strong and competitive division.

I think after Santos and Reyes he knows he's on borrowed time in LHW.

We've all seen theres no shame in terms of legacy (see Izzy) of moving up a weight class - if JBJ loses it'll be to Francis; he'll be able to collect his 30m (lol) and keep his reputation.
