In order to be an effective basketball coach one must realize other coaches' thinking. Coaches who arrogantly announce that they only concern themselves with what their own teams do put very few banners on the gymnasium wall. It's as simple as that, my friends. Prepare for all possibilities in a game by teaching your team sets to attack all defensive schemes. Otherwise, you may have sold your kids down the proverbial river before the games even begin.
Coaches change just like any other people.
Far too many in this profession fail to roll with the punches offensively and defensively. I've always been a strong advocate of halfcourt traps. I love them. Watch any college or pro game on TV, and you'll see far too many teams struggling against a spread defense in the halfcourt. This always confuses me.
