I could see Brock eliminating the entrants as they come in keeping it 1vs1 until someone like Roman, Strowman or Drew comes in somewhere in the teens. Then they can have either Brock or the other big name take turns eliminating jabronis maintaining the field small and allowing Brock to just suplex and eliminate people to the end of the match. It's gonna be a shitty rumble.
And i would appreciate Punk back in a wwe ring but "lol" at him making a fool of himself on tweeter.
