Agree with those that say the time isn't right, but we should be excited that this is a "pass" for us. If players of his caliber are old hat to us then I'm excited to see who we finally pull the trigger on.
perhaps the point being made is that pau is not so much "old hat" as just old. he is 33 now and his performances will not be increasing in the near future...or distant future for that matter.
pau is, was, an outstanding player. but at 33 his window of good years is not going to be open that much longer. also consider that he has only played more than 65 games in 1 of the last 4 seasons. so injuries maybe something to consider as well.
contrast pau's future with the current celtics window of suck, which they just threw open after trading KG and pierce. with or without pau, the celtics are looking at being bad for at least 3 years, and conceivably even 4-5.
that means pau would be 36 years old, or more, by the time the celtics are reemerging as a contender.
for any good pau might provide in the short term, the celtics are probably better off passing on him and instead investing in someone younger who can help the team into the future.
