If we're discussing current day Smackdown, doesn't WWF tv from approximately Feb-Sep 2000 deserve a mention?
The product was red hot, with great main eventers in Rock, HHH and Foley, and great strides being taken up the card by Benoit, Jericho and Angle. As well as a tag team revival (granted, a lot of that was stunt ladder matches etc, but it was hot as hell at the time), and solid to exceptional work up and down the card. Wasn't the head writer at the time praised for his sense of continuity and storyboarding each character's interactions to maintain order?
The only possible drawback in all this was match length - weren't they still operating a no-matches-thru-commercial-breaks system on Raw and Smackdown?
