they didn't rely on Goldberg. they really didnt rely on anyone. goldberg was just a sure-fire superstar and they pushed him accordingly.
if anything, the WWE are the ones that rely on Goldberg when they bring him in out of desperation. and hes a WCW guy.
if nitro was doing as badly as youre trying to make it seem, then why would they expand nitro to 3 hours AND debut Thursday night thunder?
when your ship is sinking, you don't get awarded with an additional 3 hours of primetime exposure every week.
and they still had wcw Saturday night.
the wolfpack was super-over. they were pretty much the most over "face" stable ever.
they didn't misuse bret hart at all. they gave him all the opportunities needed. i like bret but people just need to come to grips with the fact that he was a big fish in a small pond when he was dominating the WWF. he didn't have the marquee name, the mic skills or the box office presence to shine amongst the top guys in WCW. then add the fact that he just simply wasn't over like that with the WCW audience. it also didn't help that his claim to fame in the WWF was having the best matches most nights. that wasn't gonna happen in WCW where the workrate was way way higher. so he didn't even standout when it came to the in-ring aspect.
'98 WCW was good money until the last couple months. WCW didn't really hit the wall until Halloween havoc '98. most disappointing show ever, and its like they didn't even try to make up for it. then it didn't help that the WWF put the belt on the rock a month later. so now you have a rock/Austin combo basically being the new Hogan/warrior, literally right after WCW's Hogan/warrior laid an egg. it was a wrap from there.
