SummerSlam 2015 is in the bag, and now WWE look forward to the next Pay-Per-View offering. On September 20th, the company will present Night Of Champions, an annual show during which the promotion trumpets that every title will be on the line. Historically, the event has produced some sterling matches, such as last year's main event, Brock Lesnar vs. John Cena. This year, it seems unlikely that Lesnar will wrestle. At SummerSlam, the seeds were sown for yet another rematch between Brock and The Undertaker. The chances of that bout being given away at Night Of Champions are nil, WWE are far more likely to present the match at WrestleMania 32 next Spring. Regardless of such a marquee offering being omitted, Night Of Champions should have a lot to offer fans tuning in. This article is all about potential matches on the Pay-Per-View, and exactly why WWE should endeavour to make them happen. Not every contest listed is a title match, because there are only 5 major championships on the main roster. It's possible that WWE could choose to have the NXT Heavyweight Title up for grabs on the show too, but this list focuses more on the main roster titles. Just what is in store for them, and how excited would fans be for these matches?
