Wrestlemania 32 is a little more than a month away, and now that were firmly into Wrestlemania season, its time to look back at some of the great Wrestlemanias of the past. Specifically, its time to look at not just the greatest Wrestlemania of all time, but the greatest Pay Per View of all time: Wrestlemania X7. Taking place 15 years ago on April 1, 2001, at the Reliant Stadium in Houston, TX, the show was nearly flawless from top to bottom (save a few hiccups here and there; Eddie Guerrero vs. Test comes to mind). Historically, the show was also a bookend to the most successful period in WWF/E history: the Attitude Era. It was a perfect blend of great matches, great storytelling, nostalgia, breathtaking spots, and some serious shocks. Other Wrestlemanias have since given X7 a run for its money (XIX in 2003, 21 in 2005, and even 31 last year), but X7 remains as the greatest of all time. Fifteen years after it happened, the show still has an enduring legacy, and its with this legacy in mind that we take a look at all of the reasons why Wrestlemania X7 was the greatest Pay Per View of all time. And because it was the 17th Wrestlemania, we will give you 17 reasons.
