Spoelstra was asked if San Antonio's decision to sit their stars in Miami had an impact on his decision to rest his stars for this game.
"I could see how you guys can draw that conclusion, but no," Spoelstra said before the game.
Unlike Popovich, Spoelstra listed injuries as the reason for his stars' absence, which will likely eliminate the chance of the league fining Miami.
Popovich reacted in mock horror when told James, Wade and Chalmers were out.
"Are you kidding me," Popovich said in mock astonishment. "Who would think of something like that? That's below the belt. There's no place for that."
San Antonio led 45-40 at halftime.
NOTES: Two-time majors champion Rory McIlroy was in attendance, sitting alongside former Spurs forward and ESPN analyst Bruce Bowen. McIroy is in San Antonio to compete in the PGA Tour's Valero Texas Open, which opens Thursday at the AT&T Oaks Course. He won the 2012 PGA Championship and 2011 U.S. Open. ... Former Texas Rangers All-Star catcher Ivan Rodriguez received a loud ovation when he was introduced during the first half. Rodriguez was in San Antonio as part of the Big League Weekend, a pair of exhibition games between the Rangers and San Diego Padres at the Alamodome.
