Those seem like distinctions without a real difference, though. tstory_97 already cited the Spurs as 'getting it right' (per Red dictums) with Duncan and the idea that they would look to find value in places no one else is looking (international players) is consistent with Red's strategies.
Tactics need to be different today for all the reasons you cite and more.
But that doesn't invalidate Red's larger strategic approach, which is really the moneyball approach of finding assets that are undervalued or whose value is not visible to everyone else.
Danny has clearly looked to find value where no one else is looking. It hasn't alway worked (Fab Melo). But often it has (Rondo, Sully). Pressey seems to be a small such victory. Jury is still out on Faverani, Iverson.
The Spurs deserve ZERO credit for drafting Duncan. That pick was obvious and required no judgement whatsoever.
What they deserve credit for are Parker and Ginobili.
Unfortunately, it isn't clear that 'moneyball' leads to championships. It is great to seek out undervalued assets, but it is even better to get Lebron, Duncan or Shaq on your team. With only 15 roster spots, only 5 guys on the court at a time, and no minor leagues, the moneyball talk in basketball feels like just talk.
