Though 60 personal fouls were called in Game 1 of their playoff series with the Grizzlies, Spurs coach Gregg Popovich said he had no problem with the officiating, terming it "a well-called game, fair and square."

However, he cited one officiating mistake that cost the Spurs plenty.

The 3-point shot made by Grizzlies guard O.J. Mayo at the end of the first quarter, Popovich contended, should not have counted.

Referees Derrick Stafford, Ed Malloy and Pat Fraher took a long look at televised replays of Mayo's shot to make certain it had left his hand before the red light around the backboard lit up to indicate time had expired. Ultimately, the referees allowed the shot.

Popovich said he watched replays of the sequence that led to Mayo's shot, which followed a basket by Spurs guard Gary Neal with 2.1 seconds left in the quarter.

His conclusion: The clock did not start until after guard Greivis Vasquez took a full dribble after taking the in-bounds pass that followed Neal's basket.

"You can't do that in 2.1 seconds," Popovich said of a play that involved an in-bounds pass from the baseline under the Spurs' basket, two dribbles, one pass and a shot. "The clock didn't start until after one dribble and back in his hand, and then the clock started. There was no way that it was good. But that's the breaks of the game, and it's what happened. It's not a referee's call. The clock started slow."

The NBA uses game-clock operators from other teams for playoff games, rather than the local official timekeepers who work each team's games in the regular season. The referees also can start the clock, using devices on their belts.

"Anybody can make it start, but it didn't start very promptly," Popovich said.
