As for the coaches of younger kids I would stick with m2m defense. Teach them how to defend and play the game. Once you get to the higher levels such as high school varsity I believed in changing defenses to help control the tempo and keep the other team off guard.
At the beginning of a quarter or coming out of a time out is an excellent time to change to a different defense. For example, if you were running man to man defense before the time out, then switch to a zone defense for one possession. This can frustrate the other team because they are discussing what they are going to do -- like run a set play or a different offense. By changing the defense you confuse the other team. That affects their confidence, confuses them, and throws off their rhythm. This results in... ADVANTAGE YOU.
During the timeout, you were doing the same thing. Discussing what you were going to run coming out of that stoppage of play, both offensively and defensively. Defense was never a problem... but if you discussed a m2m play and they went into a zone you better have a plan B. I never wanted to give them too much in the time out or between quarters because they have a tendency to forget.
My suggestion for younger coaches is to keep it as simple as you can, run things your kids do well offensively and defensively. Hopefully you are teaching them m2m defense, preparing them for the next level. IF you coach at a higher level... switch the defense even if it is only for one possession. You can also change defense during a free throw situation.
