This was the one match I had hopes for, Triple H and Seth Rollins going at it No DQ would've been insane. Hell even if it was a standard match, Bryan/HHH is one of the best matches of the last few years so this could've been insane. My hopes for Mania seem to be dying by the second, they've already forced Orton into the WWE World Title match and Goldberg is already booked for Vs Owens at Fastlane so the world titles are dead in the water.
Undertaker is seriously in no condition to be wrestling and Roman Reigns can't carry anyone to a good match let alone Undertaker in his current state, not even that but Reigns going over Undertaker even as a heel isn't a good decision.
Cena is currently lined up most likely for Ziggler or Corbin, neither of those men are ready for a huge win over Cena so they wont be winning and it will kill their momentum. Styles has no plans. WWE could very much salvage the WWE Title with Cena retaining in the Chamber, Styles claims he wants his fair rematch outside of the Chamber and Orton has his No.1 Contender position. Other than that Cena/Styles 4 could be a seriously great match and their feud writes itself, would also be cool to have Styles be the guy who finally wins a feud against Cena.
Big Show Vs Shaq is a pisstake waste of time that is literally stealing a spot from someone who deserves it better. Genuinely angers me that Big Show takes a year off and waltz right into a Mania feature match.
Other than that I don't see any positive outcome to Mania.
