6. Kamala vs. Bam Bam Bigelow (Wrestlemania IX)
https://www.youtube.com/watch?v=CzX2QNuO9bw There was once a time where the Wrestlemania card was often so over-booked that matches were oftentimes scrapped due to time constraints. Of course, Total Divas covered the sadness of the Bella Twins/Team Rhodes Scholars vs. Tons of Funk/Funkadactlys match at Wrestlemania 29. However, 20 years prior at Wrestlemania IX, what would've been a big money match in the territory era between Kamala and Bam Bam Bigelow was scrapped from the show.
Maybe one of the truly sad losses of Wrestlemania history is that this one never saw the arena at Caesar's Palace.
