#2 Seth Rollins vs. Triple H
Shockingly, the match everyone knew was a lock for WrestleMania as early as last summer will likely be the final matchup added to that card. That may not have been the case had Seth Rollins not been injured in late January, but we're lucky the bout will even be happening at all.

For weeks, Triple H has called out Rollins and has claimed he is too weak to face him. Although Rollins isn't technically medically cleared to compete yet, he is bound to accept HHH's challenge on Raw this coming Monday to fight him in an Unsanctioned Street Fight at the Show of Shows.
The Rollins vs. Triple H rivalry dates back to 2014 when they initially joined forces, and fans were excited at the time about their inevitable split. Both men will be looking to get their WrestleMania moment when they go head-to-head on April 2, and thus there's a good chance they'll steal the show in the process.
