And it just so happens those four teams are the current four finalists.
David Stern has really blown it. The NBA right now has four out of their top six all-time greatest franchises in the Conference Finals (Chicago and Philadelphia being the other two). They should be hyping the out of that fact. Instead the NBA office is actively cowering in the face of the possibility that it might be the Spurs and Detroit facing off at the end, instead of the Golden Children Abetted by Su ious Trades.
Any smart basketball fan knows that Lakers vs. Spurs is the true classic modern-day rivalry, WITH RETURNING PARTICIPANTS EVEN, but the league publicists are too stupid to do that. (Yes, Boston vs. Detroit has history, but the Celtics have been irrelevant for over 15 years.)
If the League had a PR guy with a quarter of a brain, they would be marketing the out of old Laker/Spurs and Boston/Detroit playoff games on NBA-TV.
