#3 Seth Rollins vs Kevin Owens (No DQ Match)

Seth Rollins has built himself a tremendous faction that is taking RAW by storm. AOP and Buddy Murphy have never felt more meaningful in WWE than they do right now. But at WrestleMania, the 'Monday Night Messiah' should have to fight his own battle.
Mainly due to Samoa Joe's concussion, it looks like the ultimate blowoff to this long-standing issue will end up being a one-on-one match between Rollins and Kevin Owens. That is how this entire angle started and it makes sense to end it in the same way.

Also, it is unlikely that a major WrestleMania angle like this would culminate in a tag team match of sorts. Of course, the match will be laden with interference from both sides, depending on who else joins KO's side in the lead-up.
The best part is that it could go in many different directions and fans wouldn't feel dissatisfied, as long as the match is a fun brawl and filled with chaos. Just like how the past month has been for Owens, Rollins and the others.
