After six years away from the WWE, Shane McMahon has returned! Hes a little grayer, a little heavier, and a bit slower, but not slow enough to shuffle his way out to the ring for a match with The Undertaker! Its the battle of the 51-year-old man with a bad hip and the 46-year-old son of the owner at WrestleMania. Okay, so if I can stop being cynical for a moment, the match is at least fresh, intriguing, and contains huge storyline ramifications. The fate of Monday Night Raw hangs in the balance. If Shane wins, he gets to run WWEs flagship show however he sees fit, which would hopefully bring forth some massive changes. The product badly needs a boost, and perhaps Shane OMac can be the one to deliver. Its still unclear if the prodigal son will have any actual power behind-the-scenes. But if he does defeat The Deadman at Mania, the company is likely to at least make some bold on-air moves to make it feel like a new era has truly begun. There are a lot of things that fans have been clamoring for, whether it be a change in the booking philosophy, or a host of new talent joining the fold, or compelling storylines for the mid-card. This is a chance for the company to excite the fanbase again, and to help stave off a heavy WrestleMania hangover. Here are seven things that Shane McMahon can do to shake up WWE.
