Yeah, why wouldn't the Sonics wait until today? It's possible that they wanted to move things up to see what was available for themselves. Maybe they got the final offers from the serious suitors and made a decision. Financially the trade works out for the Sonics in that they will probably be able to reduce their payout to Barry by more than the differential in salary they took on. Still, it is interesting from the Spurs' perspective.
Artest to SA could possibly help them land better talent moving forward. Horry had his moments in the last postseason (ie Denver series) and you hate to see the Spurs give up such a clutch shooter because you just know there's going to be a time when that is needed in the playoffs. Also, to land Artest you know the Spurs are going to have to give up some combination of their prospects and future picks.
Still, think about (not to make Ghost wet himself) a 10 man rotation like...
Starters
1 Parker
2 Finley
3 Bowen
4 Duncan
5 Oberto
Bench
1 Stoudamire
2 Ginobili
2/3 Udoka
3/4 Artest
4/5 Thomas
