5 reasons why RAW defeated SmackDown Live 6-0 

#2 To prove RAW is the dominant brand

And it has always been the main brand in McMahon's eyes

Ultimately, it all boils down to what Vince McMahon thinks, doesn't it? RAW has always been the dominant brand and SmackDown Live has always been an afterthought. Having the main brand squash an inferior brand, at least in his eyes, will not bother him.

WWE brass may believe that top RAW superstars like Brock Lesnar and Ronda Rousey may be too valuable to take the pin against a SmackDown Live star. And those matches were foregone conclusions anyway, as a result. Even in the under card, having a team like AoP lose momentum with a loss would not have served well, over time.

WWE Creative had the dominant brand come out on top and prove that three hours of RAW consists of the actual superstars. This could help revive interest in a brand with declining ratings, of late.
