The issue is not that RVD is overrated. Hell, Meltzer himself says that RVD is a flawed worker, who, theoretically, should not be over.
The problem is that he WAS over, ungodly over, over to the extent that he was cheered louder and more enthusiastically by the fans than the majority of the WWE's own guys - and instead of capitalizing on that, the WWE just jobbed him out until the fans, by and large, stopped caring.
It's just another example of the WWE royally fucking up a golden opportunity.
