We have to remember that San Antonio basically handed two games where they were ahead in the last 12 seconds to New York. Game 2 in San Antonio where with them ahead by one point and only about 12 seconds left, Wemby threw a pass to I believe Castle’s back which Brunson stole and then got fouled. Absent that mistake, San Antonio was very likely to have won that game. And we also saw what happened at the end of game four, when San Antonio again had the ball with about 11 or 12 seconds left, and ahead by one, instead of trying to dribble out the clock and get fouled, Fox foolishly went for a layup try which was blocked.
Absent those two gross and unforced errors in critical situations, I suspect San Antonio wins the series. So I think overall they did a good enough job. You can’t account for people throwing the game away in the final seconds.
