#3. Randy Orton as the WWE Champion won't make a big difference to the ratings

It's no secret that RAW and SmackDown ratings have been going through a big slump - hitting record low numbers. There's no doubt that the lack of crowd and crowd reactions have something to do with that, but WWE will still want to do the best they can and attract the best viewership they can.
That's the reason why they've been putting many PPV-quality matches on free TV - such as Randy Orton vs Big Show a week ago. Even Asuka vs Sasha Banks was a PPV-level match shown on free TV.
Either way, Randy Orton is going to be a major needle-mover, as he's doing the best work of his career. At this point, it's going to be hard to imagine anyone who can singlehandedly bring the ratings back up.
While Randy Orton would make for a great Champion, his 14th reign doesn't seem necessary and it won't bring back major ratings.
