I can't really see the Celtics as doing the same things as the Suns, ziggy, though your comparison is very interesting, to say the least.
The Celtics wanted tested experience to win right now, whereas the Suns have been successful for several years now and apparently do not expect to be drafting all that high for some time, so why carry rookies on the roster who are less likely to contribute right away anyway?
Boston, on the other hand, was in a bind. While some of those young legs might develop into decent NBA style players, why take that chance if you can get back to the playoffs for the next two or three years by trading for Ray Allen and Kevin Garnett and win now?
But it is those thirty year old legs that has me pondering the wisdom of this move. I can see several playoff years for Boston coming up - in fact, with the weak competition the East has to offer, that is a worthy betting guarantee - but unlike the Suns, who should be ready to start drafting again just about when their current team ages gracefully into the Arizona sunset, the Celtics will be starting completely from scratch and drop from contending like a rock once the legs of their thirty-somethings start to slow way down.
