Very solid post.

I personally think the Spurs should ditch the 2010 strategy. If it is about getting the best value for your team the time to compete for players is when no one has or no one wants to spend their money. If you look at the rosters across the NBA you will see that the majority of teams are in great position to compete for players in 2010. When the few true franchise players are taken then you will still have a bunch of teams with a lot of money and few players. Then 2nd tier players will be overbid for because teams will be in somewhat of a panic mode. Even high quality role players will end up getting overpaid. This, of course, is bad news for the Spurs since this is the area they have excelled at. By ditching the 2010 strategy the Spurs can turn what is now perceived as "nothing worth trading for" into something of value. If you take the posi on that Mace should be a part of the team past his current contract that will leave you with basically Bowen, Oberto, Bonner and Finley as tradeable pieces next summer.
You never want to limit your options, so I wouldn't go as far as to say ditch 2010, but you're pretty on the money in your analysis of the overall landscape of the NBA and how the Spurs should be looking to take advantage of the value presented.

So what might the Spurs be able to get over the summer. First off, I believe it is a year to use the full MLE. I think teams will be hesitant to commit to players so maybe Rasheed Wallace for 3 years and about 18 million is a nice addition.
Rasheed is a done deal if he's willing to come for the MLE. As far as value, talent, fit, the guy just makes too much sense to not be welcomed as a Spur.

I know some like to say Pop would never allow him to setup shop in S.A. because of his loudmouth antics, but they would be fooling themselves.

I can't remember if it was when the Artest rumors came about, but Pop made a point then (and has since repeated when pressed) that being a choir boy was not a requirement. Rasheed is definitely the type of player Pop was trying to appeal to.

Rasheed is not Artest, or a locker room cancer like a T.O. His teammates love him, he's unselfish, (almost to a fault) he's got a good BBIQ, He plays D, and oh yeah, he's a champion.

I'm going to be one happy son if Timmy's got "Roscoe" watching his back next year.
