Before this discussion devolves into a number of irrelevant arguments, I wanted to say that I think your logic is sound and your course of action would be beneficial to the Cs.
It's obvious that Ainge is going to try to re-enact his moves from the summer of 2007. He knows "stars" win championships. You can always find role players. It's the stars that are difficult to get. Three options: Draft, Free Agency, Trade. The draft takes time and luck. Free Agency has never been a Boston strong suit, and many young stars are re-signing with their teams. So, Ainge is left with trades.
Realistically, it will take at least one more season to gather enough draft picks and young assets for trading. Remember, he spent the mid-2000s gathering assets for the eventual trades that brought in Allen and KG. I believe he started this process again (while also extending the window for a Pierce-KG-led team) when he re-signed Green and Bass, and signed Terry and Lee. These are all trade-able assets. And, if you don't agree, just look at the guys he traded for Allen and KG - Szczerbiak, West, Gomes, Telfair, Green (the Gerald one), Ratliff, Jefferson, the #5 pick (Green, the Jeff one), and a swapped first round pick with Minny. He has better talent on the roster now. And, who is to say he won't end up with the #5 pick next season if Rondo is held out to the All Star break and neither Pierce or KG continue wearing green.
I have long thought Love would be a terrific addition to the Cs, but perhaps due to his long injury history, Ainge could push harder for a player like Aldridge.
I think most fans would be excited come 2014-15 if the roster included Rondo, Green, Sully, and either Love or Aldridge.
