10. Psycho Sid Vs. The Undertaker (WrestleMania 13)
The problem with the story of Undertaker challenging for Sid's championship is that there was no story. Plans for WrestleMania 13 changed drastically, with the original main event set to see Bret Hart get his win back over likely champion Shawn Michaels, evening their high-profile series. In early-February 1997, McMahon took the championship out of the planned Hart-Michaels match, claiming it was 'too predictable'. Sid was to defeat Michaels on February 13 with Hart's interference, but Michaels bowed out with the infamous knee injury. Hart got Steve Austin instead, which was for the best. As for Undertaker vs. Sid, their story paled to Hart/Austin, and amounted to little more than stare-downs and simplistic brawls. Not exactly an exciting marquee build.
