Do you actually think so?
Just look at it. The definition for jump range is:
A player with a higher jump range will find that the effectiveness of his jump shot decreases less with distance.
So the closer to the net, the better the shot. And how do you get closer? By jumping.
And you know what. Shoei also suggested jump range. And he's an Australian division 1 member. So if I'm crazy so is he lol.
