Not joking: One of the "conspiracy theories" I have is that DW chose Vitor because of his habit to hurt himself in training. Like he is almost hoping for the same situation to happen to really try to put the pressure on JBJ and force him into the situation. I don't really buy it, but if it happens and I am just going to have to scream "I KNEW IT!".
Even if it happens it doesnt mean that in the slighest.
You should go buy Chaels book "Voice of Reason". He covers this point exactly.
