wrong. when wade was drafted the heat got better, but they brought in shaq and pat riley became coach again. thats not rebuilding through the draft. duncan put the spurs over the top in 99, but that was 1 player that came in and made difference. they went from winning just 20 games in 98 to winning 37 in just 50 games the following year. you cant even mention detroit. every player on that team was a veteran. mention 1 championship team (within the last 2 mileniums) that has sucked for more than 2 years?
The Spurs ARE the PERFECT example of building through the draft, and filling the holes in around those guys. They got their stud Duncan via the draft. Then, when he made them too good to get lottery picks, they mined the later portions of the draft for their two otehr studs Manu and Parker. Their entire big 3 came from the draft.
Then, they filled in the gaps around them. Oberto was drafted, not sure where and when Bowen came from off the top of my head. Finley, Barry, Horry were added as role-playing veterans via free agency.
But they did the bulk of it through the draft. They didn't wildly overpay through free agency, or do it via trades, they used free agency to fill the holes left by their draft.
Think about it, for as much rumor as there always is regarding superstar trades, they rarely get traded and they rarely move via free agency. Kobe, Dirk, KG, Duncan, Wade, Lebron, Melo, Amare, Marion, Parker, and Yao are all still on the team that drafted them.
The only exceptions are AI (and the YEARS it took to trade him should illustrate my point), Shaq (who basically forced a trade), Nash and McGrady. The point is that teams usually draft their superstars and hang onto them. They rarely if ever move via free agency or trades...
