I have to disagree with the authors review of Vaders WWF run.
He(the author) did comment that Vader arrived with much fanfare and for the first year at least, he was pushed as the companies monster heel!
There's reference at the time that Vader was supposed to win the World title but got injured and the WWF employed Sid Vicious especially to hold the belt for a while.
To me, Hogans idiocy didn't hurt Vaders WWF run, I got the impression from watching the WWF at the time that they didn't know what to do with him!
After they jobbed him out for a while they just lost interest.
With hindsight, we have seen the WWF/E do the same thing to other monsters such as Big Show and Kane - difference being that Wight and Kane weathered it and enjoyed countless pushes..., as well as countless pointless jobs!
I would say that Vaders career in the US at least, was irreversibly damaged by his WWF tenure, rather than hogans cuntishness! I think in his last televised match, he got squashed by Bradshaw!
For a true Hogan casualty - Bam Bam Bigelow to me is one of the biggest wastes of potential!
