If Savage omissions still surprise anyone, they really need to get with the program. Does anyone know for sure what the deal is? (No I won't mention That Urban Legend...)
I'll try another theory besides "that urban legend" : Since Hogan and Savage hate each other, maybe Hogan got in Vince's ear and convinced him to "erase" Savage from history. Told him something like doing business with Savage would mean an end to their business relation. Since there's more money to be made with Hogan, Vince decided to go with it and agreed to never mention Savage again.
I'm not sure, but I think Savage isn't even on the "Greatest stars of the 80's DVD".
He's definetely not on the "Greatest Stars Of The 80's" DVD. As far as Vince and the WWE are concerned, Savage never existed.
