#2. UFC heavyweight champion Francis Ngannou vs. Jon Jones
There’s no doubt Francis Ngannou vs. Jon Jones would be the biggest heavyweight bout in UFC history.
Reigning heavyweight champion Ngannou is the most feared knockout-artist in the sport and has finished many former champions. Jones, on the other hand, is viewed by many as the best pound-for-pound fighter when active.

It remains to be seen how the former light heavyweight champion fares at heavyweight.
But this bout would definitely generate interest if billed as the biggest heavyweight bout of all-time. In his most recent fight with Ciryl Gane, Ngannou displayed his significantly improved wrestling and handed him his first career loss.
Even though Jones has fought elite strikers in the past, he would need to be cautious of ‘The Predator’s' power.
‘Bones’ grappling could be the story of a potential bout with the heavyweight champion. This heavyweight battle would be significant for both their respective legacies in the sport.
#1. Former UFC two-division champion Conor McGregor vs. BMF champion Jorge Masvidal
It wouldn’t be a WrestleMania style event for the UFC if it wasn’t headlined by their biggest star Conor McGregor.
The former two-division champion would surely be the main event should the promotion host a sell-out event at a large North American stadium.
In terms of his opponent, he would have to fight somebody with a large following, and Jorge Masvidal checks that box.
It’s rare for the promotion to have their two biggest pay-per-view draws competing in the same division.
Despite not being in the welterweight rankings, ‘The Notorious’ is no stranger to competing at 170lbs. He fought Nate Diaz twice and Donald ‘Cowboy’ Cerrone at welterweight and is 2-1 in the weight class.
Despite losing to welterweight champion Kamaru Usman and Colby Covington, ‘Gamebred’ is still the ‘BMF’ title holder. If the title is on the line, that would add another layer to the buildup and take it up a notch.
