8 Things WWE Got Right At WWE No Mercy 2016
7. AJ Styles Retains
This was the only correct decision for the outcome of the match. Ambrose and Cena should move towards a feud with each other now, and whilst Ambrose isn't quite CM Punk, there is something of the Cena/Punk chemistry between the Lunatic Fringe and The Face That Runs The Place. Cena vs. Ambrose should provide WWE with a great story as they head towards Survivor Series.
Styles is the best wrestler on the entire roster today, and his title reign deserves to run all the way to at least springtime 2017. As for who challenges him next, that isn't so clear. Randy Orton came up short in the main event, and as a result will probably continue grappling with the Wyatts.
There aren't a huge amount of babyface challengers left on SmackDown (Ziggler? Heath Slater? Kane?), but Styles is popular enough to pull off a tweener role if he were to feud with, say, Wyatt (leaving Harper and Orton to go at it) going forward. Either way, Styles was the right (and only) winner of the show-opening triple threat.
