3. Respect the Tag Team Championship on Both Shows
With all singles championships organized with each show, the Tag Team Championships would be the one championship without a direct tie to a specific show, which gives it the freedom to fill time on Raw and be represented appropriately on Smackdown.
In a way, the Tag Team division would require the most depth since it’s going to fill two shows. That will make the champions look strong, or the Championship can be interchangeable between many different teams which gives the division a huge sense of equality. That is always compelling when a division is based on equal performers instead of one great team and bunch of good, or okay teams.
