DS9 had the benefit of a separate showrunner and writers IIRC, but yes, the TNG crew were essentially trying to double-up handling both TNG and Generations at the same time.

That said though, the writers have also talked about how after seven seasons they were basically running out of plotlines, finding it increasingly difficult to come up with something that they either hadn't already done, or it had been decided previously that they weren't going to do.
