I think it's a great idea and now with the Cruiserweight Classic wrapping up, it would be a great time to launch another show to air in the CWC timeslot on the WWE Network. Last year's tag team tournament took place on NXT shows and the finals took place during NXT Takeover: Respect.
If they decide to do this year's tournament on a separate show and they can bring in some outside teams from independent promotions, then they can follow the same formula as the CWC and sign some of the standout teams to the main roster. Smackdown Live is in desperate need of some depth in the tag team division.
Finn Balor and Samoa Joe won the tournament last year.
