He was knocked out by a guy 200lbs bigger than him and lost his title to a former WCW, WWE, WHC and ECW champion. Regardless of how much of a semi-jobber Show has become over the last few years he is still a major force to be reckon with. They gave Show the win to complete his legacy (pardon the pun) as a grand slam winner.
He then loses a match via distraction. Hardly a burial. Losing via a clean pin after Kofi had beaten him with no interference or distraction would have been different. And it was all part of the Rhodes/Show feud. Which will probably end with Cody winning the title back.
When he starts losing week after week to multiple faces, with clean wins, it becomes burying.
