Seth Rollins claims he is the best in the business, holding the World Wrestling Entertainment (WWE) heavyweight title and the United States title at the same time.

It has been some time now since Rollins snuck and stole the WWE title from under the noses of Brock Lesnar and Roman Reigns dating back to Wrestlemania 31 and thus far, he has found a way to stay at the top of the WWE, clean and dirty.

He added the United States title to the mix, something he won at WWE SummerSlam thanks to the aid by Jon Stewart. And for holding the two titles, he has to defend both in one night at WWE Night of Champions.

As far as his chances with Cena are concerned, everyone seems to believe that Cena will get even and regain the U.S. title. That, of course, is up for debate and it would be safe to wait until Sunday to see if that is indeed the case.

How about the WWE title picture? While it seems a bit off to see Sting end up winning the title, it could boil down to a choice between catapulting Rollins all the more in the WWE ranks with a win or winning the title and then losing it if Sheamus decides to cash in.

Rollins could come out with a win but just the same, a cash-in could ensue. Competing two times in one night and against tough wrestlers in Cena and Sting will certainly take its toll so don't be surprised if Sheamus sees it as the opportune time to strike.

As far as winning over Sting is concerned, there are some who believe that a Rollins win is not exactly the right time to do so. With that said, a cash-in could come before a winner is declared.

Either that or a disqualification win or no contest could also happen. 

WWE Night of Champions will kick off this Sunday at the Toyota Center in Houston starting at 8 p.m. EST and 5 p.m. PST.
