#4 A match against Triple H at WrestleMania 31
CM Punk and Triple H never got along that well. As mentioned before, claiming The Shield was his idea was one of the reasons Triple H lost the respect of Punk.
Punk would then go on to own the cerebral assassin on countless occasions including the infamous pipe bomb promo in which punk referred to Triple H as Vince McMahon's doofus son-in-law. Punk would take shots at Triple H on marrying his way into the business and constantly got on the game's nerves. This feud had all it takes to go for a long time.
If punk were still in the WWE by the time, we would've seen witnessed CM Punk vs Triple H at WrestleMania 31 instead of that abomination of a match with Triple H facing Sting.
