Cody Rhodes goal in becoming WWE Champion has nothing to do with who the champion is, just so long as he wins the title. It ultimately doesn’t matter if he’s the guy to end Roman’s reign of terror.
Sami Zayn potentially defeating Roman Reigns for the title in his hometown of Montreal has the makings of one of those pops and moments that people would remember forever. Sami can essentially only be champion if it’s at Roman’s expense.
Where do you see Sami Zayn defending against Cody Rhodes at WrestleMania landing as even a remote possibility? The crowd would be hot as they’re obviously both popular but there would also be way less chance of a fan backlash to a potential Cody win since Sami still would have gotten his moment. Or Cody loses and you get another long term story with him working his way back up before finally winning the big one while Sami gets to run with the title a little longer, maybe dropping it to Rollins or back to Roman before Cody gets his next shot.
This then leaves Roman available to face someone like Rock or Austin in the top non-title match as Roman plans to destroy one of the GOATs before vowing to reclaim his title after WrestleMania.
0.00000000000000 percent chance.
