So I go to bed thinking about a trade idea last night, and work out the details in the morning. Next thing you know, 5 pages of thought provoking discussion around off-season moves, trading aging stars, and the salary cap. Good stuff all around.
Here is why you have to trade Allen AND Garnett at the same time. No team is going to swap an up and coming star for an over the hill star at the same position. Roy for Allen is not going to happen, so you have to cross positions.
I think Utah does the deal because Ray Allen is the best player for probably another year, Boozer will resign, and they will not have room/cap for Millsap. Getting rid of Kirilenko is just gravy, and the cost is a promising prospect (Koufos).
Chicago does this in a heartbeat.
Portland is the tricky one, because the deal does not make sense talent-wise. Deng is only one year older than Roy, and plays a solid game. Not an upgrade, but he is a good egg and replaces 80% of the production.
I think the real reason they make the move is for Greg Oden. If you look at what Garnett has done for Kendrick Perkins, and apply that to what he could do for Oden, you start to understand why Portland might be willing to part with Roy. If this team expects to make it to the promised land, it will be on the broad shoulders of their young center. To hasten his development, they need a leader like Garnett.
Maybe Chicago throws in a little sweetener, and maybe we forget about the pick, but those are just minor details.
As for Boston, the Roy for Allen switch at off-guard is about even now - and projects to be a major upgrade in a year or two. Done and done. Millsap is the real questionmark. Is his production this season an anomoly, or do his favorable comparison to Elton Brand project for the duration of his career? Can Rondo consistently give you 14+ ponits per game if he takes some of the shots left behind by KG's? Will Koufos exceed all expectations?
If the answers to those questions are yes, this new team can and will compete for championships well beyond the Pierce-Allen-Garnett window.
