I'm totally with JayDerek on this one.... I'd MUCH have rather have the series end while it's on top rather than stay around for the sake of doing so. Everything right now is being set up perfectly for the proper closure.

As much as I'd miss the series, I'd have no problem revisiting it from time to time on dvd..

I don't want to see the series take a turn for the worse, but I wouldn't at all be worried about that happening for at least 2 more seasons (~30 episodes). 7 seems like a magic number.

I would only classify it as "stunt casting" if they were to advertise it as a selling point: "Guest starring Jimmy Johnson!" I never heard a single mention of Johnson being on the ep except for when Johnson talked about it during one of the halftime shows this football season. He certainly wasn't shown or mentioned in any of the promos for this week's ep or even at the beginning of the season.

To me, it seemed almost like maybe he's a fan of the show and had someone on the inside who could write him a small part. I would be curious to know how exactly he happened to get involved.

I had no idea that was Johnson.
