Diesel’s Title Run

Did Vince McMahon/The WWF always plan for Diesel's Title reign to be as long as it was, or was it just on the fly booking?  I always felt at that point that Vince was trying to look for the new Hulk Hogan to carry his company, and he was determined it was going to be Kevin Nash come hell or high water. 

He was planned to be champion for years like Hogan, but he flopped and Bret Hart was told sometime in the summer that he was getting the title instead.
