This would also be that special WrestleMania moment for Bryan also. And most importantly it will be what the fans want as they wouldn’t settle for anything other than Bryan standing tall when the show goes off air.
As far as Triple H is concerned he could easily insert himself into a feud with Roman Reigns as explained here. Thus it would be a great card all around with matches like Roman Reigns vs. Triple H, Batista vs. Orton vs. Daniel Bryan and Undertaker vs. Brock Lesnar with Bray Wyatt vs. John Cena match being a bonus.
This card would be the best way that creative could book everyone and make the fans make happy in the process as well.
So the next time Bryan comes out and asks for a match at WrestleMania , Triple H should easily reject the offer because no one want to see the thirtieth anniversary edition of WrestleMania being ruing by a stale main event featuring a duck champion and jeered baby face.
