#3 Retirement match angle with King Corbin

There are very few individuals in the pro wrestling industry today, when the business has been exposed, who have the kind of heat that Baron Corbin does. A lot of heels today are cheered for the great job they're doing, but in King Corbin's case, he is booed in every arena across the world.

Last year, King Corbin was responsible for retiring Kurt Angle and he could certainly do the same with John Cena at WrestleMania 36. Imagine the kind of heat that King Corbin would have if it turns out that he's the man who retired John Cena.

After WWE Super ShowDown, one assumes that the program between Roman Reigns and King Corbin will finally be done and dusted for good. While the matches have been good, it is a feud that has gone on way past its expiry date and needs to end at once.

I know that John Cena and Baron Corbin have faced off in the past, but he wasn't nearly the heel back then that he is right now and a promo battle between the two men on SmackDown would be money.
