Anyone who wants Ainge to build a contending team around Rondo and Green should be p---ed. Last offseason, plenty of legitimate players were dumped or ignored because everyone was enamored by Lebron, Love, Bosh, etc.
I absolutely think we could have had Asik or Afflalo for a great price, but what about Channing Frye?
There are only 2 good reasons to not go after Channing Frye:
1. He's taking time from worse players who you want to develop.
2. You are still trying to stay out of the playoffs and get better draft talent (aka TANK).
What about making the Parsons offer. On that one I doubt Parsons would leave a contender for us, but we could have at least made an offer.
I have no problem with these moves (or absence of moves) because I think development and drafting should still be our goals. But if we get nothing for Green and Rondo, it's a complete waste and an inconsistent strategy.
Respectfully, I don't think you understand the concept of the salary cap, or the Celtics lack of room underneath it, if you think the Celtics could have made an offer to Chandler Parsons. Same is largely true with Channing Frye, although you could have made a competitive offer for him if you let Bradley walk. You also forego Evan Turner, Tyler Zeller, Marcus Thornton, and Josh Powell in this scenario. If you'd rather have Channing Frye and some minimum salary vets than all those, yes, Frye was an option. But Parsons never was.
You can throw out other names you'd have liked to sign instead, but to sign any single one of them, you'd have needed let AB walk, and not make the trade that brought us Zeller and Thornton, probably miss out on Turner (you'd have 20% less to offer him), and also release Bogans before you made the trade that brought us Powell. It'd also cost you a future 1st and two future 2nds. All that for a single free agent making no more than about $9 million this year. I don't see how that'd make us a more competitive team.
Honestly, aside from breaking the bank for that superstar to pair with Rondo (which he tried to do with Love), there weren't a ton of great options that he had. A lot of the C's contracts were designed to expire with KG - once we moved from the Big 3 era a little early, there was bound to be an extended transition, barring someone falling in your lap.
