It's one thing to revise history but starting your point with "It's funny to me," is just sad. We can all tell you are actually putting in the effort to claim these bullshit.
No. Leon was not considered THE top contender. For the last four years, Leon was either overlooked or the subject of ridicule. He was ridiculed for being the victim of Masvidal's "three piece and a soda." He was ridiculed for how his fight with Belal ended. He was ridiculed for getting rocked by Nate Diaz. People completely overlooked him and his win streak in favour of Colby because of how dominant (and boring) Usman was in their first fight.
Let me give you an advice, speaking in a condescending tone will not magically make your bullshit narrative stick. You can refute my points all you want by bringing up how Edwards just beat Usman. Only thing it'll prove is that your reading comprehension is shit.
