The NBA is expected to have a new set of rules in place for the start of the 2017-18 season that Gregg Popovich and Steve Kerr might not like.
The league will reportedly install player-resting restrictions in September, according to USA Today, in an effort to prevent teams sitting healthy players in regular season games.
There will be consequences for teams that do not follow the rules, though it is unclear what they will be.
A practice made popular recently by Popovich and adopted by coaches around the league, resting star players diminishes the on-court product for fans and sponsors, but allows players to remain in top shape throughout a rigorous 82-game schedule.
The new rules will force Kerr to rethink his strategy for the upcoming season.
"Given the way we're going to approach next year, we're going to play 100-plus games again, trying to get back to the Finals for a fourth year in a row. So we have to pace ourselves, find the right balance between improving, winning games and resting," Kerr said in July.
"I feel like we have enough depth where the way the NBA has promised to fix some of the scheduling, we're going to probably rest one or two guys in any given game. No more than two in one game. We're not going to do the four or five unless the schedule is a disaster again. But I think we can sit Andre (Iguodala) and Shaun (Livingston) strategically and be comfortable with it because of Patrick (McCaw) and Nick (Young) and Omri (Casspi). I'm pretty comfortable."
Depending on what punishments will be levied against teams that rest players, Kerr might feel a little less comfortable.
