WWE Royal Rumble 2017: Predicting All 30 Entrants
20. Shawn Michaels
Given WWE have a 60,000+ seater stadium to fill, and given that the Royal Rumble takes place in his hometown, it'd be daft not to have Shawn Michaels involved in the show. His appearance has been rumoured since the venue was announced, and while most of the talk revolves around a "guest host" role or a potential dream match with someone like AJ Styles, a Royal Rumble appearance makes perfect sense.
WWE would likely advertise HBK's appearance on the show in advance so they can squeeze as many ticket sales as possible, but they don't have to announce his participation in the Rumble. Let him open the show with an in-ring promo, then stun the audience with a decent run halfway through the Rumble. It'd give his ageing body the protection that a singles match wouldn't, and surely blow the roof off the Alamodome.
Odds of Winning: Slim.
