Hmm, let me see.
Wyatt - Not credible enough yet, find him kinda boring tbh. I don't really want him to win.
Reigns - Would be a good choice, but not now. Save Reigns/Lesnar 2 for a bigger stage.
Joe - I'd absolutely love to see Joe win, he's been great since his debut and I'd love to see him and Brock kick the absolute shit out of each other.
Rollins - Again, Rollins would be a great choice. He's got some momentum and I think he and Brock could put on a great match.
Balor - Now, here's the final man. I'd absolutely love to see Balor win. I think him and Brock could put on a great David vs Goliath match.
Pretty much, I'm excited for this match. People are saying the MITB match is gonna be better but I disagree. This one has more star-power and just looks better imo.
