#3 KofiMania

There are honestly no words that do justice to the movement known as KofiMania. Not only is that evident by how organically the fans got behind Kofi Kingston from the very beginning, but also by just how brilliantly the company planned the whole thing. In fact, this was arguably some of their best underdog storytelling and it captivated fans at every turn.
While KofiMania did feature a lot of uniquely timed twists and turns, the biggest one had to be that WWE took the chance and did this in the first place. The company took a chance on a guy that was seen by many fans as a solid wrestler who would be a mid-carder for his entire career and turned him into a legitimate champion, complete with a title victory at WrestleMania 35.
Kingston would go on to prove himself as a main eventer during this time and provided some great matches in the process, but this was still a big risk for WWE to take because it came completely out of left field. Luckily for the company, the combination of The New Day's star power, Kingston's underdog story and his undeniable charisma was enough to make this whole time period a success.
In the end, hopefully this is the start of WWE taking more chances like this. Think about it! The move worked for guys like Kingston, Daniel Bryan and other underdogs. Why not keep digging and see what kind of gold they can bring up to the main event next?
