Like you are five? It’s been a while since I did that with my son, but I can try.
This guy Jones, he tha man. He was the bestest of the best earlier. These days, he is also one of the best, but older. This other guy, Stipe, he was also great but so old he's retired. The Jones guy has one fight left and then he is retired as well. He wants to defeat Stipe to prove to himself he is also the bestest in the HW division even though Stipe isn’t. This doesn’t matter to Jones, he has a point to prove to himself and to some people on Twitter and Facebook. They are also old. This third guy Dana, now he is the boss of the whole thing, like kingpin from Daredevil. He loves Jones and hates Stipe. Most of all though, he loves money and lying to people. So now this Dana guy is lying about Jones and Stipe being the greatest HW fighters so he can grab a lot of money. Thus he is making this fight happen at any cost. Some weird dudes on this obscure forum called Sherdog (like Instagram, but more retro, because they are also old) don’t believe his lies and can’t understand why everyone else is buying it. It’s because of the power of media, politics and such, but that lesson is for when you are older.
