The New Day rocks. That isn't just a chant anymore - it's indisputable, undeniable fact that the trio of Big E, Kofi Kingston and Xavier Woods is one of the best things about the WWE product, something that will probably remain true for at least as long as it takes for their merchandise sales to taper off.
The group have essentially accomplished (although not quite to the same degree) what The Rock did 15 years earlier. On paper, their act seems corny and even a little embarrassing, but in practice it just works, and few fans can resist the opportunity to join in a communal chant-along given half a chance.
It hasn't all been plain sailing, though. Despite what their future Hall of Fame package may say, New Day wasn't an instant success, and since its three members all led their own individual careers before being thrown together a couple of years ago, they each have their own back-stories too.
All of that is to imply that there have been one or two missteps along the way, and given WWE's proclivity for rewriting or else just heavily embellishing history to suit its own ends, it's likely that some of this stuff won't be getting an official airing any time soon.
