I was happy working for the N.B.A., but to be honest, I decided that I'd probably get back into coaching. I missed the teaching, I missed the games, I missed the competition.

I don't know concretely if it's due to superstition, but any time a new rule is implemented into the NBA or a new piece of equipment or a new technology, there is always a transition and adjustment period by players and coaches and anyone involved with the game.

The message here is you cannot, under any circumstances, throw an object at an official. You just cannot do it.

The hand check has always been a part of pro basketball.

Once you begin reviewing judgment calls, which in basketball there are many, you put yourself on a very slippery slope in terms of what could be reviewed, and ultimately the number of reviews that could take place that would make it unwieldy.
