During the playoffs, the word "adjustment" is used as part of the NBA vernacular far more than during the regular season. This is with good reason.
During the 82-game regular season, coaches have some leeway to try new offenses, defenses, matchups and styles of play. Not every loss is crucial, so a coach often will allow his team to continue to play a certain style beyond the point of failure. This assesses limits and shortcomings, and adjustments can be made to further sharpen the team's play to an optimum level.
In the playoffs, however, adjustments must be precise and immediate. After all, in each series, a team has just three losses to work with. There is no time for extended experimentation, and the margin for error is quite small. While these adjustments are mainly done at the macro level -- strategic changes made by a coach -- many adjustments are made by each player.
With the Boston Celtics down 1-0 in their first-round playoff series with the New York Knicks, Celtics guard Jason Terry has significant adjustments to make in order to be a factor in Game 2. Likewise, Knicks center Tyson Chandler was ineffective, and if his team has any hopes of a deep playoff run, Chandler must make adjustments of his own.
