And this point in particular,
What makes a team a unit, what makes this sport fun, is the ball.
Players became players to play with a ball, so let them have it as much as possible. And let's build around the idea of having it all the time. But the ball burns you. Give it to a colleague as soon as you can. Play quick, play simple. And when you lose it - get it back as soon as you can, because it should hurt not to have it.
