I think this might the exact team we see ay the year.
Danny isn't trading his assets before the trade line to make frustrated fans happy. Immediate change isn't always good.
If Danny can't get young players and picks for Ray and KG, they aren't going anywhere because their cap space is a much more valuable long term asset to the team than mediocre talent on long term contracts.
If Danny isn't getting expiring talents and lots of picks for Pierce, he isn't going anywhere because he is still a viable NBA asset and because they can amnesty him and get $16 million more in cap space.
If Danny can't get another NBA star for Rondo, he's not going anywhere.
So everyone else is discardable but is trading them going to really get the Celtics anywhere?
This team is, IMHO, more likely to look exactly the same at the end of the year as it does now than to look completely different.
