#2 The future has arrived
The narrative that constituted the break up of The Shield back in 2014 was centred around Triple H recognizing Seth Rollins as the future of WWE, and all those years later that prediction by Triple H has not come true as yet.
And while most might say that Rollins has arrived due to his multiple Wolrd Title wins and main event status, the truth is that while Rollins is a top star in WWE, he is still a bit far from being the top star in the company.
Therefore, a match with arguably the most hated heel in the company would give him that top spot, it is clearly evident that WWE has chosen Seth has the heir to their babyface throne, and by being in a match with the biggest heel in the company, it is his crowning moment to truly become the top dog in WWE.
