A ton of different factors throwing this off for me (Brock, DB new champ, Smackdown becoming the A show in 2019)
I think they'll do AJ wins it from the 1 spot (when's the last time we had a 1 spot winner?)
I would give it to Drew Mac, though. That guy is a star and should be getting the main belt. I wouldn't be against him vs. Brock for the main title somehow.
They would never do it, but I would also consider Finn Balor winning it and moving over to SD for a Bryan/Balor or AJ/Balor match. SD needs another guy and I think Balor could make that jump. I love Joe, but he's been hurt like four times now.
