I always think about this - Rondo, Pierce, Durant, Jefferson and Perk would have been good enough to get a title? What do you guys?
I don't think so. Durant wasn't ready for a few years and Jefferson needs to play C. They'd need to move Perkins to the bench and find a PF. Obviously Rondo + Durant gives you the foundation to build a contender easily by adjusting the pieces though.
Danny has said he knew he could get KG for just one of the top two picks (aka keep Jefferson and other pieces probably). I doubt he trades for KG with them though.
I actually think he trades for KG if he gets 1 or 2. Basically the trade would have been the pick plus salary filler and no other value. Boston would not have had Ray Allen though, but would have kept Jefferson, Delonte, Gomes, Telfair, Gerald Green, as well as the picks (two firsts in 2009 though the Minnesota one was protected), etc. It would have been a very interesting team with Rondo/Telfair, West/Allen, Pierce/Green, Garnett/Gomes, Jefferson/Perkins. I doubt that team wins the title that first season, but I think it would have been positioned pretty well over the next few and would certainly be in better shape now (assuming they kept Jefferson).
I do think the better hypothetical is acquiring Ray Allen but KG still says no and Boston then goes after Pau Gasol. I suspect Boston could have kept Jefferson using Ratliff as the main salary, a couple of firsts, and some of the other young guys (maybe Big Baby, Perk, Green, etc.). That trade seemed on par or better than what LA was offering at the time (though Marc Gasol turned out great for the Grizz and was a guy they specifically targeted).
