My one other theory on this DC vs Stipe fight is this :
I believe that just before this fight happens, literally the day before the fight, I think Dana White is going to ask DC for 5mins of his time and he is going to sit down with him in a private setting and spend 3 or 4 minutes telling DC means to the UFC, praising him to the skies and all that, and then the punchline will be this : "Daniel whatever happens Saturday night in the Octagon with Stipe -- please promise me NOT to retire in the cage after the fight. Let's just talk first, ok?"
I think Dana will offer Daniel half a bank-vault of gold to have one more fight. Maybe DC vs Ngannou or Jones and promise DC 10million dollars. Some massive offer that DC would find very very hard to refuse. Even if DC DOES retire in the cage on August 15th, I still think Dana will make him a massive offer for one more fight. Jones or Ngannou. This is what Dana does.
