Precisely.
Here's a three way trade I concocted: Blair to the Hornets (who only have three rotation bigs) for next year's 2nd, then Neal with the 2nd to the Bucks for Sanders (with Udoh and Henson, he's redundant and has no chance at cracking their big rotation; plus they were interested in Hinrich, so they'd obviously like another guard).
That clears out the logjam at guard and gives the Spurs the type of athletic, shot blocking big -- who can play both big positions -- that they need.
As for Duncan's contract, despite what some idiots may say, this is a really good deal. I wouldn't have thought he'd sign for 3 years initially, but it's quickly become all the rage now with the over 35's in the league, so at this point I'm not that surprised by it. Championship or no championship, it's nice to know he'll be around for another three years.
'Tres, I was thinking the same thing with Ginobili, only for $20-22M.
