The rest of the NBA also has changed. Perimeter defenders are more restricted than ever. More and more teams are using small, unconventional lineups, relying on speed instead of size. As a result, the Spurs used the regular season as an experiment, employing a variety of defensive schemes as well as different combinations of players to match up with the Suns, SuperSonics and Dallas Mavericks.
"I think it's an evolution every year, but more this year than years past," Duncan said. "To seeing how people have been playing, to seeing the success Phoenix had early in the year, knowing we have to adjust to that and play against that come playoff time, I think was just a great vision by Pop and understanding what the game is going to be like."
