The ECW Championship suffered several indignations after being brought out of retirement for the WWE's third brand. Chief among these was a match which really should have been celebrated - the first time the belt was to be decided in a WrestleMania match. Although champion Chavo Guerrero and challenger Kane were hardly the most synonymous wrestlers with ECW, the title would finally gain recognition as something worth defending on the grandest show of the year. Instead, fans were forced to watch the championship bout last a mere 12 seconds, decided by a single Kane chokeslam. It firmly solidified the title as a belt far below the WWE and World Heavyweight championships, one treated as something of a joke by the booking staff on the biggest stage of them all. https://www.youtube.com/watch?v=cGJGfGJUP7U
