World Wrestling Entertainment (WWE) Night of Champions is fast approaching and Seth Rollins could probably be doing his best to make sure that he is fit and right when he takes on two matches for the night.

In a way, the scenario comes with the territory of Rollins wanting to be the best of the best, being the WWE Heavyweight champion and the U.S. champion. Both titles have to be defended and so Rollins will have to work overtime to keep both.

For the U.S. title, Rollins will be facing John Cena. After being cleared by the WWE, the former U.S. champion is expected to pull out all stops to reclaim his lost belt. There are some who believe that the belt will likely be reclaimed by Cena but the real concern here is how brutal or draining the match would be.

Rollins should expect to be heavily worn down by Cena in this one, especially if Cena locks on his patented submission hold. That plus Cena's artillery, Rollins could find himself drained after this match.

And then there is the big one, perhaps the biggest match of his life as he faces former World Championship Wrestling (WCW) icon Sting. Despite the fact that Sting has aged, he is expected to give Rollins a dose of why he has become a legend.

Could it be a crowning at the end of the final bell? Well, perhaps if the WWE wants it to be. But it could be a short reign if Sheamus decides to cash in against the Stinger.

What if Rollins retains? Well, he could either be attacked by Sheamus as well or leave the night bragging about how good he is. If he defeats Sting, would he be the greatest?

Well, maybe not because there is still one man he has yet to face, Sting's conqueror — Triple H. Could that be lined up next?
