It's 2014 and your name is Bilal Tahtahi, a heavyweight fighting out of Belgium. You lost your debut, but are offered a fight against some guy who is 1-1. He won his first fight via armbar, and then lost a decision. Seems like a fair matchup, so you sign to fight Francis Ngannou.
You wait over two years for the cobwebs to clear, take one more fight, lose via TKO, and retire. But you fought Francis Ngannou.
