I actually thought of a pretty crazy idea that would get me to watch the Jinder Reign. So, The New Day are due to arrive on smackdown as soon as Kofi's injury is completely healed. And, I feel like even though they've been getting solid reactions still, that if they just come to smackdown doing the exact same thing with no changes, it's really going to wear the stable dry pretty quickly.
SO, while I don't think they should turn heel again, I think they should be going after a different goal, in particular, trying to see Kofi Kingston to winning the WWE Championship. And I have couple reasons why I think a Kofi/Jinder feud could work well. Firstly, there is the trio vs. trio dynamic of the New Day against Mahal/Singh Brothers. Secondly, New Day is very much a comedy group, and one thing Jinder does do fairly well with is comedy thanks to his stint in 3mb, he'd know how to sell it. And finally, it'd just be a nice mish mash of style. Because Jinder and gang would be trying to be overly serious, while New Day would handle the entertainment side of things.
....plus I just really want to see Kofi win the big one ;p
