Plenty of factors went into the San Antonio’s decimation of the Miami Heat in Game 3, in which the Spurs shot 99 percent from the field and at one point went 44 minutes of game time without missing a shot (all numbers approximated).

There was sharp ball movement from the Spurs, leading to open shots galore. There were lazy closeouts and slow rotations by the Heat, affording San Antonio’s role players to dominate the first half. There were the Spurs making the hustle plays, getting on the floor for loose balls and straight up ripping steals away from Miami’s ball handlers.

While some of the onslaught could have been prevented by the Heat playing a little harder, as Miami coach Erik Spoelstra said after the game, the Heat actually played okay offensively, although not at the historic pace the Spurs were blazing. San Antonio actually shot 59 percent for the game, with a 66.4 effective field goal percentage, while shooting better than 75 percent in the first half. basketball-reference.com.

Again: awful.

Gregg Popovich blinked first in this series, changing his lineup and moving NBA.com. Guess what? All but one of them includes one of either Chalmers or Cole.

That leaves Spoelstra with some tough decisions to make with the Heat two losses away from their season ending. Finals adjustments are commonplace - Mike Miller saved the Heat’s season when he slid into the starting lineup in 2013 - but the Heat are much thinner this year and lack a true option to replace Chalmers and Cole both. Some of the adjustments will come in how the Heat play defense, and it’s safe to assume their tenacity on that end will pick up.

The point guard play is going to have to improve exponentially, too. It could spell doom for the Heat if it doesn’t.
