Improved half-court offense (like the "good olde days) that features constant strategic screening, cutting, passing (mostly bounce, not overhead floaters, especially not cross-court to be picked off). Also, don't start a dribble without a clear purpose, and don't pick up the dribble without a purpose either to shoot or pass immediately). No just standing and watching team-mates. Do box out aggressively while on defense, even on opponents well away from the hoop. All of those, please. Oh, and talk constantly on defense.
