I disagree, at least in the coming off-season. I hadn't realized how close the Spurs were to the cap already, and with 7 expiring contracts (Brown, Horry, Johnson, Marks, Massenburg, Robinson, Wilks), there's a good chance, given the increased cap figure, that the Spurs will actually go under the cap again in Year 1. Even if you add in the salary of the #28 pick, if the cap goes up as much as has been reported, the Spurs will have plenty of breathing room and will likely be under for 2005-06. They'll certainly be below the threshold for a number of years to come, too, which I'm sure is music to Peter Holt's ears.
One thing to consider about being under the cap -- should that come to pass. The Spurs will have some flexibility in terms of making trades because they will be able to bring back more salary than they send out (to some extent). It might be only $2-4 million in year one, but if you could, say, deal a $6 million contract, you could, in theory at least, bring back a $10 million player. Just a thought.
