Emmett is getting old and was never the fastest, but he still has his nasty power. I am not confident he wins or loses this one but Lerone is maybe and overrated prospect so who knows.
Yes the Guru did a long series exposing Jones and I do believe something else is also going on with him, he's off. Some rumors say it was a side effect of certain types of steroids he may use.
So Aspinall is upgraded to being the undisputed Heavyweight champion as Jones seems to have exited the sport in ignominy. As a notable aside and not to gloat, the UFC is now devoid of black champions, something to note for any subscribers to the caste narrative.
