#1 To compensate for no Elimination Chamber match
For some weird reason, WWE loves to leave the RAW Tag Team Championship out of Pay-Per-Views, despite having more than enough space on the card.
Take, for example, the Royal Rumble. There was easily enough place on the two-hour pre-show for a tag team title match. Instead, WWE had Gable & Roode go up against the odd pairing of Scott Dawson and Rezar.
The sad reality is that the RAW tag team division is still neglected, and perhaps they've decided that they want the title and its matches featured on RAW more than PPV. Either way, whether it's been "relegated" or not depends on your perspective. The Cruiserweight matches get on the kickoff show, while the RAW Tag Team title matches hardly even get on the show.
Regardless, it's a good thing that The Revival won, and hopefully, this will mean a change to the RAW Tag Team division, which has needed a revival of its own for a while.
