So would anybody trade are Awesome Backcourt, For a top ten big man in the NBA. And a bunch of other assets. I would.
Excuse my ignorance, but who is the top ten big man in this trade?
Off the top of my head, Dwight Howard, Yao Ming, Kevin Garnett, Tim Duncan, Carlos Boozer, Pau Gasol, Chris Bosh, Amare Stoudemire, Dirk Nowitzki and David West come to mind as players who would all qualify for the distinction of "better than any big man named in this trade."
I'm sure there are some embarrassing omissions on my list (Al Jefferson, anybody?), but they were the 10 names quickest to mind - and my point here is that while a certain Portland power forward may turn out to be an excellent overall player, I think you're stretching LMA's immediate value a bit.
And regardless, if I were the Celtics, I would have desire to trade a stud backcourt (including a point guard who could be here for the next decade) for a Portland core that doesn't include its best player (Roy) or its highest-ceiling player (Oden). They're not trading either of them, and rightfully so. But the Celtics don't need to deal simply for the sake of dealing.
On a final note, given your thread title, it seems worth weighing in that I find this deal less compelling than the more widely rumored Rondo-Ray deal.
