I like rooting for Junior, he is a great happy guy like most people are not and he fixes heads in spectacular fashion. He used to, as you mentioned sort of, some have speculated the two beatings he got from Velasquez affected him.
By the way, since August he has been under review by the USADA for a possible PED violation. he has said he always supported fair competition, and that maybe a supplement was produced with something off in it. I wonder why it takes so long, I occasionally google his name to see if any new news happens, nothing recently.
Assuming he gets back to things in good order, I do want to see him against Ngannou. Junior actually wrestled a little bit in his first Miocic fight, and tripped him, the latter I think is part of why the judges gave it to him. He might be able to be more than just boxing and give Ngannou a thorough ride.
A rematch with Overeem would also be good, maybe it would go diametrically the other way, except that Overeem said after the first fight that he had Junior’s rhythm figured out. So maybe I don’t know. the first was boring except for a front kick that crotched Overeem and the knockout in the second round.
Sure, Lewis could be interesting.
As to a fourth fight with Velasquez, I haven’t kept up as much with what is happening with Cain, but after Junior said after the Rothwell fight that he is a boxing guy, forget everything else, I just don’t want to see it.
