Sounds like some of you have completely forgot about how awful WCW was in the 21st Century...WCW was doing completely shyt numbers and was a HORRIBLE promotion at the time...do you naysayers even
remember the Goldberg/Nash/Russo "shoot" angle?
Goldberg refuses to follow the script! - YouTube
A lot of wrestlers were given futures that they wouldn't have had if the company simply folded like it would have eventually did.
I'm not saying that Vince killing other promotions didn't do a disservice to wrestling, but WCW (and ECW) were different. It was beneficial, no doubt (ECW being another one, as it had went bankrupt, but now we see that it has more of a legacy had it simply just faded away, IMHO)
WCW had been hemorrhaging tens of millions of dollars for YEARS. If anything, it hurt WWE to buy those companies because it made the roster ridiculously huge.
Competition is always great, but these rival promotions couldn't compete for a reason.
It was actually good for wrestling that WWF bought WCW & ECW, IMHO...
