I guess it's just a pure coincidence that TNG got substantially better once the Roddenberry box was lifted?
It was lifted half-way through TNG's first season (not the third season, but midpoint of the first). It was really Berman's show from that far back in the series.
If TNG got "substantially better", it had more to do with Michael Piller signing on as executive producer by season three than Berman.
