A lot of fans who pick their favorite fighters then lie to themselves afterwards about how well they'll do.
Think of it as a kind of MMA Politics. People who didn't like Colby but liked Tyron weren't going to consider recent performances. They weren't looking to talk themselves out of picking Tyron, LOL. So they lie to themselves that this could be where he turns things around. They'll tell themselves that Colby isn't as good as people say he is, and that Tyron is going to knock him out.
I imagine those are the same people that make bookies a fuckton of money, too.
