Nobody ing wanted to make a deal with the Spurs; you look at the trade deals that happened and the Spurs didn't have the contracts or players to make a deal unless you throw in George Hill, Manu Ginobili, or DeJuan Blair which would be dumb to do.
Mason Jr. almost got traded to Miami for a second round pick but their trade exception retired. Theo is a ty and older version of Marcus Camby except he only statpads blocks and little to nothing else; Bonner, McDyess, and Blair all contribute more. Theo is better than Ian though but when it comes to garbage minute players, la-dee- ing-da
No trade would've made the Big 3 younger, Parker healthy, or greatly improve this squad and there was none that the Spurs could really capitalize on.
