The camera angle is shot looking up to everything, and the point of focus is two basketball players jumping. The photographer is just off of the court and gets everything in frame, from the lights, the net, the ball, all ten players on the court, the fans, the score board. The image has a long depth of field where everything is in focus so we can the emotion and drama of what is happening. The composition of the photo with the two players jumping and what seems to be every single other person staring at them to see what is going to happen is powerful.
This is a good description of the elements that contribute to the composition and meaning.
