I had no idea there was anybody who thought Francis Ngannou was a more decorated MMA fighter than Jon Jones. Jon's won more title fights than Francis even has fights in the UFC. Francis lost to Derrick Lewis, is 1-1 with Stipe, and nearly lost to Gane, who Jones only took 2 minutes to beat. Conor was at least 2-0 in title fights in 2 divisions at the time, and even that they had to handicap with an older smaller guy. Francis got flatlined in 4 minutes by a guy 20 lbs smaller than him.
The premise is wrong anyway because nobody wants to see Jones box either, nor would anybody say it's interesting if Conor tried to box Dmitry Bivol.
