1. Injuries
Amid all the excitement and chaos of professional wrestling, it's sadly easy to forget that the health of the performers should matter most. From time to time, we're all guilty of overlooking how much each WWE superstar puts their body through in the name of entertainment. Lesnar is 38, not exactly in the athletic prime of his life, while Undertaker is now 50. The risk of lumping both in a notoriously dangerous stipulation is clear. Much has been made of WWE's recent reliance on old stars for a nostalgia kick, but that comes with an uncomfortable side-effect - the risk of injury is far greater, and the severity of each knock could become far worse. This was thrown into sharp relief at the most recent PPV, Night of Champions, which saw Sting suffer a nasty injury to his neck and back. Ultimately, Hell in a Cell 2015 could be remembered for all the wrong reasons - potentially even the site of Undertaker's forced retirement. Surely WWE would have been wiser to delay the feud a little further, and have the pair settle their differences in a more conventional contest at WrestleMania 32.
