Some say teams of prior decades are automatically much better (talent wise) then the teams of today due to the expansion teams over the years (i.e. watered down league).

I disagree, as I don't see how just a few expansion teams can make that much of an impact. I believe older teams merely look better due to a decrepitude of fundamentals and an increase in complicated defense.

But then again, the 80's Celtics had four or five HoF'ers at one point.
