Really, though, my point isn't that Ainge will try to trade for Faried or that the Celtics should go after Faried, it's that Ainge will go after talent that he can get for cheap even if it doesn't fit positional need. If he makes a trade, he will probably bring back someone who isn't being discussed in this thread.
I actually don't think Ainge will go after Faried because he is signed beyond this season, but if the price is sufficiently cheap, he might change his mind.
