As has been implied; WCW wasn't very good at knowing what to do once they acquired a certain talent.
One kind of ironic thing I remember about Bret Hart's WCW run. Bret was a guest on the NBC talk show Later, and they showed a clip of a spot he did where he kayfabe quit after pinning Goldberg. Bret smugly repeated something that Vince had said, which was "If WCW got Bret Hart, they wouldn't know what to do with Bret Hart." He apparently believed that the angle would eventually be successful.
