The objective of the offense in basketball is accuracy of each attempted
shot. This is a well known fact; however, only the better shooters practice
correctly and work at improvement during the off season.
Since most of this shooting practice sessions are alone, every player
must be his own critic. This means every player must understand the
mechanics that affect the success, or failure, of every shot. Every player
must know his range and know what is a good shot.
Therefore, before examining the techniques associated with the various
shots, here are the principles at work in every scoring shot from anywhere
on a basketball court. These principles are divided into two parts:
- Mental aspect.
At no time is psychological conditioning more
critical than when shooting the basketball in a game. Knowing when to
shoot and being able to do it effectively under pressure distinguishes the
great shooter from the ordinary.
Regardless of how much he practices, or how well he conditions himself,
only a modest amount of improvement is possible in speed, reflexes, or
strength. History gives many examples of players able to achieve greatness
despite mediocre physical talent. Usually, however, such successes are due
to determination.
Concentration: is the fixing of attention on the job at hand and
is characteristic of every great athlete. Through continuous practice,
good shooters develop their concentration to the extent that they are
oblivious to every distraction.
Ability to relax: is closely related to concentration. You
often hear great shooters have "ice water in their veins".
Watch a good foul shooter as he approaches the foul line. They
usually begin the ritual of adjusting the feet and bouncing the ball
(nearly always a set number of times). As his/her eyes open wide in
sighting the basket, the concentration is so intense, there is little
wonder that he/she is undisturbed by the crowd or game pressures.
Confidence: That is a "gut certainty" the ball will drop through
the basket without touching metal.
Although, a good shooter never takes a shot that he is not confident in
making, he often misses. Therefore, the probability of making any given
shot is somewhat less than 100%. Clearly, then, when we say, "Don’t shoot
when in doubt," we have something different in mind than we do when we
say, "Don’t take a low-percentage shot except in desperate circumstances."
There are reasons why a player might lack confidence when confronted
with a shooting opportunity having a good statistical probability of
success. He may be off balance, had his confidence shaken by a string of
misses, or have a lapse in concentration. As Coach David Hayden used to
say, "one often contributes to the other."
Every player experiences off nights when nothing works. An equally
familiar phenomenon is that a player’s returning to peak form in the
second half after a miserable first half. This ability to make a mental
recovery is like the ability some players have of recovering in mid-air
after an off-balance take-off.
Physical Aspect: Shooting a ball and connecting with the target
involves the following factors:
Sighting or locating the target: The difference between sighting
and aiming is that in aiming, a device (for example, a gun) is visually
aligned with a target; thus, visual attention is equally divided between
the pointer and the target. In sighting, however, the eyes are used
merely to locate, or fix, the target in space, and the computing of an
intercept trajectory is left for the brain.
Some coach once said, "To demonstrate the brain’s ability to
determine a trajectory to a known location, close your eyes and touch
either your nose or your ear lobe with a forefinger. To convince
yourself of this ability in relation to a visually fixed target, focus
your eyes on a nearby object and, without aiming, point your finger at
the object. Notice that there is a strong tendency for your attention to
shift from the object to your finger and that considerable concentration
is required in order to remain focused on the object."
Notice, too, that when concentrating on the object your eyes open
quite wide. The reason it is so important for the eyes to remain focused
on the target is that they, too, are a kind of computer, continuously
updating a three-dimensional fix on whatever is being held in focus.
Naturally, the smaller the area focused upon, the smaller the fix, and
the greater the potential accuracy.
This brings us to the problem facing a basketball player of not
having as his real target not a concrete object, but an open area just
over the lip of the basket. Since his eyes can not focus on an empty
space, the best he can do is to select a sighting point as nearly on
line with the intended trajectory and as near the real target as
possible.
When making a bank shot, the shooter solves the problem on a spot
related to the painted rectangle above the basket. For all other shots,
however, he must decide upon a sighting point somewhere on the rim.
Personal preference determines whether the point selected is on the
front or the back rim, but each player should decide on one or the other
and stick with that sighting point for all similar shots. Then, for
every shot, he should fix upon the same number of cords, while conscious
that he wants to drop the ball either just beyond front of the rim, or
just before the back of the rim, whichever point he chose to sight. The
sighting point must be held in constant and clear focus from the moment
the shot is begun to the completion of the follow-through.
Body Balance: When properly balanced, a shooter can coordinate
the efforts of each muscle to produce a force in the direction of the
basket. Although the degree of balance may vary from the near perfect
stance of a two-hand set shot to the last effort recovery of an
aggressive drive-in.
The shooter’s ability to control the trajectory of the ball is
directly dependent upon his/her ability to control the acceleration
forces generated by his own body. However, it is doubtful whether a shot
ever succeeds unless, at the moment of release, the shooter has enough
control to complete a smooth, continuous follow-through.
Some players have such body control they can hit baskets from
positions impossible for any other player. Each player must learn
whether or not he is in a position to take a shot and complete a
follow-through that will leave him in the position to rebound a missed
shot.
Generating the force: In their book, Basketball Concepts and
Techniques, Bob Cousy and Frank G. Power, Jr., tell us, "From
physics, we know that when several forces act upon an object, the effect
is the same as that of a single force equal to the vectorial sum of the
force components..." In simpler terms this means, the more horses
pulling in the same direction, the greater the horsepower.
They go on to explain, "To a weightlifter, this means that it is
possible to synchronize the efforts of leg, back, shoulder, and arm
muscles to lift a heavier weight above the head (as in a jerk) than is
possible with the arms alone (as in press). To a basketball player, it
means that the force he can impart to the ball ranges from that required
for a long two-handed set shot to that required for a tip-in
a few inches from the basket."
Therefore, beginning at the ball, each of the following add to the
total transmitted force:
- A forward action of the wrists and fingers.
- A sudden extension of the arm, snapping the shoulder and elbow.
- Rising to the balls of the feet.
"Since the force imparted by a muscle under strain is difficult to
control, best results are obtained when all muscles can be brought into
a smooth, coordinated effort that is within individual limitations."
Obviously, with a jump shot, much of the energy generated is
converted to altitude. The remaining force required must be provided by
arms, wrist, and fingers.
Timing or rhythm: The timing of a shot begins with getting the
correct foot down for takeoff (jump shot) and ends with the
follow-through and recovery. In a set-shot. Perfect timing
results in a smooth, continuous thrust from the floor upward, developing
a peak force at the fingertips, the instant before, and sustained
through, fingertip release.
In a jump-shot, body momentum decreases rapidly to zero and
the shot must be timed so that fingertip release occurs just prior
to the highest point of the jump. Any non-synchronized
acceleration of the body, or its members (for example, jerking the head)
will directly affect the path after launching of the ball.
Hand-eye coordination and fingertip control: All forces imparted
to the ball by the shooter should pass through the fingertips. This
technique allows the fingers to make fine trajectory adjustments at
release and provides a soft natural backspin.
By stating that the optimum trajectory is that which results in the
ball’s entering the basket at the highest possible angle commensurate
with the lowest possible velocity, we shall have said all that can be
said about trajectory. Therefore, a high arching shot is recommended.
Combined with a soft natural backspin, a medium to high trajectory
results in the "soft touch" kind of shot that even if slightly off
target, will either drop in or hang on the rim for an easy tip-in.
In adjusting the hands preparatory to shooting, the shooter should
space the fingers comfortably to hold the ball firmly in his fingertips
and on the heels of both hands. The palms are held slightly clear and
the three middle fingers aligned perpendicular to the seams. Players
should practice their feel of this until this adjustment becomes
instinctive as soon as they catch a ball.
Follow-through: Throughout the act of shooting, the brain
continues to compute the precise amount and direction of the force
needed to reach the target. Although these computations continue
automatically in what computer people call, "real time," there is
sufficient lag time to make compensations impossible for any abrupt
accelerations at, or before, the instant of release.
Therefore, success depends upon the constant sighting and a smooth,
continuous build-up of propelling force that reaches its peak at the
instant the ball leaves the fingertips. This means that a follow-through
period in which the forces generated are allowed to diminish is an
essential part of the shooting sequence.
