I think Driving is the ability for a player (who already has the ball) to get closer to the ring, passing by opponents, in order to get a closer shot (e.g. lay-up).
Therefor, yes I believe driving might be important for everyone. Every player who has the ball, and sees a way to 'drive' through to the basket might use this opportunity.
However, I feel this might be more important to (power) forwards and centers, since they mostly try to get close to the ring when taking a shot. Point Guards and shooting guards will look for opportunities to pass the ball to other players, or take distance shots when they are open themselves, and therefor will imho use less driving...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
