UFC 203 predictions

The UFC is putting a card with two stories. On the one hand, the UFC heavyweight title is up for grabs. There's a top contender bout directly under it as well. On the other hand, a person whose only qualification to even be in the Octagon is having the right kind of celebrity, and a willingness to try new things, is making his MMA debut. It's a bizarre conflation of opposites as the UFC hosts a show in Cleveland for the first time.
What: UFC 203
Where: Quicken Loans Arena, Cleveland, O
