Outside of the Lakers vs. Celtics. Sixers vs. Celtics have the best rivalry in NBA history

[fourkicks44]

No two teams have played against each other in more playoff games or playoff series than Philadelphia and Boston.

I've had some disappointments but 2002 was the biggest let down. That one really hit hard.

Who won each of those series?

[Prometheus]

It's a good rivalry, but we Sixers fans care way more about it than Boston fans do. Their franchise has been so comically successful that they really don't give a shit about us, or anyone else except the Lakers for that matter.
