#1 It's a fresh rivalry

The Orton vs Styles scoreboard stands at 3-1 in favor of Orton right now. Although it would lead you to believe that this rivalry already has four matches to its name, and is overexposed, that's not the case. The last two times Orton pinned AJ, they barely interacted with each other. The other two matches that happened, took place over a year ago.
Both performers have come a long way now, with both undergoing considerable character development. Those two matches on SmackDown Live could be considered as a litmus test for a grander stage. This feud is incredibly fresh, something which this WWE product sorely needs.
Just like Styles vs Cena, this could raise the blue brand to an upper echelon. These are two bonafide legends, sureshot first-ballot Hall of Famers, the best of their generations, slugging it out at the Superbowl of wrestling.
