Hogan’s drawing power in 1987

From my memories of reading the 1987 recaps on the blog, Hogan's house show business was a bit sluggish post-Wrestlemania III.  After all, who was going to buy One Man Gang or Killer Khan as threats after we all saw Hogan beat ANDRE THE GIANT clean?  Was this
the first sign of a (minor) slip in Hogan's drawing power, as he now needed a credible opponent to sell out the house, as opposed to filling it on his name alone?  Or was this just a blip (he did really good business with Boss Man in '88 as I recall)?

I'd say it was a blip.  There was never any suggestion from the Observers that things were slipping until 1990.
