#1 Have major names appear as commentators
Nothing to take away from anyone's credibility, but one of the biggest reasons why SmackDown was a much better show than RAW this week was due to the presence of Triple H as the commentator and narrator of the lue brand's show.
The way he introduced us to the Performance Center and then carried himself throughout the show - taking jabs at Michael Cole, taking up different roles of a cameraman and make-up artist and whatnot, that was as entertaining as it could get for the fans watching the show from their home. Unfortunately, there was no such thing for RAW and it pretty much felt slow and dull due to it.
The point is, WWE needs to bring their attention to this issue and try to fix it as such small things drastically change the entire appearance of the product. While Triple H might not be able to do it every week due to his other commitments, WWE has enough legends and show-mans who can do what the Game did on SmackDown last week.
I'll even go as far as to say that maybe Vince McMahon himself can appear as a guest commentator at WrestleMania 36 just for the surprise factor of it.
