Throughout WWE history, there have been some massive potential matches that fans would love to have witnessed but which, for one reason or another, never actually happened. Whether it was because the talents in question were working for different companies or one retired before the other achieved fame, or possibly the WWE missed the boat and the prime of the superstars' careers had passed, the reasons are varied and frustrating. The 90s seems to have suggested more of these potential blockbuster matches than any other, mostly because the WWE roster was packed with legendary superstars and future Hall Of Famers. These would-be matches could've changed the entire landscape of the business and perhaps inspired a butterfly effect that would make the sports-entertainment foundation we now know totally different. Technically, a couple of these matches might have actually taken place as a dark match or at a WWE house show, but even if so, these 15 match-ups were never given the chance to shine on the right stage or in the right specific year. As such, they all feel like phenomenal missed opportunities. The passing of time has only made it clearer just how big these missed opportunities were.
