As for RVD's match with HBK, I believe that it's HBK who's the cause for the low rating. I mean, according to rumors, the Armageddon buy-rate was the worst one in years. And who Main-Evented that one ? HBK. And as for RVD/Kane vs. Three Minute Warning, I'm a huge RVD fan and I flipped channels that first match and didn't even watch the second one. If WWE refuses to put RVD in any type of angle, then where is the incentive to watch ? Notice that these "ratings bombs" - Storm/Regal, Three Minute Warning, Kane....they don't have any type of angle and haven't had one for months. Meanwhile, Steiner, Black Gold, and Jerichristian HAVE had good ratings, while having angles as well. Coincidence ? Not really.
I'm kinda getting off-topic here, but the point is that it's difficult to call ANYONE a ratings-bomb. Especially RVD, considering he hasn't gotten an angle in months and has repeat matches against people like Three Minute Warning.
