Fun fact, two of those five things are known to be counterproductive, but coaches still do them, presumably due to social expectation and/or job security. Conservative play calling with a lead, particularly on defense, is known to reduce your chances of holding the lead. Sticking to more balanced tactics leads to losses that look more spectacular, but fewer of them. And depending on how you look at the stats, the "icing the kicker" timeout either doesn't really work, or only works if done before the offense is set, which is not when most coaches call it.
