Consider Road to El Dorado, Spirit:Stallion of the Cimarron and even Antz. Not the best films and they didn't do great at the box office either.
Since his departure, Disney animation sometimes hasn't been as great, but I'm pretty sure Tarzan wasn't influenced by him and I know Lilo and Stitch wasn't influenced by him at all. Both of these films did great at the box office and were relatively hits among the public and critics. So there has been some high points during the "post-Katzenburg" era at Disney and maybe Disney "jumped" a little when he left, but they're still in the game (and still doing better than DW animation where Katzenburg is the head, at least up to this point)
Yeah I forgot about Tarzan. That one was up there with what I've come to expect from classic Disney animation. Box office aside, though, I think Dreamworks has had a better track record of quality animated than Disney has in the same span of time. I would also argue that, aside from just the animated features, there have been more quality films that have come from Dreamworks than from Buena Vista.
The more I think about it though, I would have to agree that the death of Wells had more impact. Not only did it lead to Katzenberg's departure, but it really had a ripple effect throughout all of Hollywood and even affected other studios.
