#5 The Many "Firsts" The Show Might Have
Finn Balor, Asuka & Shinsuke Nakamura have confirmed matches for Wrestlemania. This will be their first time on the big show. Elias, Braun Strowman & Bobby Roode are three others who can potentially have their first Wrestlemania this year. On top of that is The Miz having his first defense of the Intercontinental Championship that isn't on the pre-show. Probably the most impressive "first time" is that The Usos might have their first main-card match this year.
This year's Wrestlemania may see the biggest amount of fresh blood in years as a new roster of talent has grown and established itself, while some old faces have managed to re-invent themselves. We might also see the first one-on-one match Matt Hardy has had in the event since Wrestlemania 19. This year presents a unique sense of freshness that years before did not have.
