Doc Rivers discussed his strategy in using his coach's challenge during the season, adding that he disagrees with the analytics that says he should use it anytime during a game.

"It's going to be something that is going to take a little bit for us to get used to and when to use it. My guess is we are going to use it first half, if it's one of your better players that you think didn't commit a foul, you may use it to make sure he gets the foul back. Analytically they said we should use it anytime, which I don't agree with that," said Rivers.

Mike D'Antoni became the first coach to use the challenge system during a preseason game between the Rockets and the Clippers.

"It's going to be a little adjusting. It takes a while to get used to. We don't have the regular flow of information that we'll have in a regular game. They'll tell me before that I should go out there and challenge," added D'Antoni.
