#4 Form a tag team
Dolph Ziggler needs a resurgence in WWE, as does the tag team division. Right now the tag team division is treading water, and if WWE doesn't do something then the whole division will be sunk. Ziggler is in the same dire position as tag team wrestling in WWE.
The Usos, The New Day, The Bar, and The 'reunited' Shield have made tag team wrestling cool again in WWE. While these four teams are making magic happen, we can't keep watching the same two teams every Monday night, then turn around and watch the same two teams every Tuesday night.
2017 has been the year that tag teams became endangered in WWE. American Alpha, DIY, and Enzo & Cass were all broken up, The Hardy Boyz, The Revival, and TM-61 are all injured, and The Colons...actually, where are The Colons? WWE needs to replenish the tag team division, and teaming Ziggler up with another superstar may be the answer. We have seen Ziggler team with other superstars in the past, and he always looks like he is having fun.
Plus, having held the World Heavyweight Championship, as well as the US and Intercontinental Championships, a Tag Team Championship would make Dolph Ziggler a Grand Slam Champion.
