#1 Reunite old tag team - Chad Gable and Shelton Benjamin
Before Chad Gable moved over to RAW, he was a part of the SmackDown tag team division with Shelton Benjamin being his tag team partner. The duo had a good run as a team and they even battled for the SmackDown tag team championships on multiple occasions.
If you look at Chad Gable and Benjamin right now, they are both directionless. Hence, it might be a good idea to reunite them and strengthen the sinking division. As mentioned ahead, Rusev and Shinsuke Nakamura are the only credible heel tag team on SmackDown Live thus, the heel team of Benjamin and Gable will give more variety to the tag team division.
It is always better to use the available talent to the fullest than to call up superstars from NXT and have them stack up the roster. This is the golden opportunity for WWE to give the careers of Benjamin and Gable a fresh boost-up.
