Basketball; What does this mean?

Question

"The preparatory position of the body is very important to the jump shot and even at this point there is debate over foot position. Players are often told to square up toward the basket, even though it is commonly thought that a slightly staggered stance, rather than a completely square stance, facilitates a better jump shot. If the dominate foot is placed a little in front of the other foot, it is thought that the body will be more stable and better aligned. Ideally the ball, wrist, elbow, and shoulder should be on a plane aligned with the basket, and it is argued that this is best done in a staggered or homolateral stance rather than a completely squared stance."

Answer 1

It means that there are two coached ways of shooting a jump shot.
1) Feet even with each other, "squared up"
2) Dominant foot slightly in front (right handed shooters have right foot a little in front when jumping up)

#1 used to be the most taught method, but it's saying that #2 is being taught more now because it helps keep your shoulder, elbow, and wrist in a line with the basket. Practice what a free throw would be with both feet right on the line and look at where your elbow and shoulder point to. Then put your good foot a bit in front and see how it changes.

Answer 2

It seems pretty self-explanatory to me:
The paragraph explains that when taking a jump shot, your accuracy will improve if your shoulder, elbow, wrist, and the ball are aligned toward the basket. It further explains that some feel the feet should be even and facing the basket, while others find it better to put their dominant foot (usually the same side as the shooting hand) slightly forward relative to the other foot. Many players also do that when shooting free throws.

Answer 3

the basket and the ball combined
