Areas
of Strength
The 1-3-1 zone is strong against the inside game and teams that
have good shooters at the wing. The 1-3-1 offers the best defense
for trapping.
Your
best defensive rebounders are kept near the basket. Two tall forwards,
played at the wings, can contest vertical penetration. A quick
baseline defender can intercept many inside passes.
Point
guards have trouble getting shots against this zone. Frequently,
teams that ordinarily attack with a point will switch to a two
guard front. Teams that attack by driving and screening find it
difficult against the 1-3-1 zone.
Big
centers find it difficult to operate inside against the 1-3-1
zone. The power of the defense is in the middle which makes it
difficult to pass inside. The big center can be fronted and played
behind.
The
1-3-1 defense neutralizes the popular triangular overloads. Because
of the positioning of the perimeter defenders, three defensive
players can always match the offensive overload.
Areas
of Weakness
Good corner shooters and good guards can destroy the 1-3-1 zone.
A good rebounding team can get many extra shots against this zone.
Many coaches will send three offensive rebounders to the weakside
to overload the lone weakside defensive rebounder.
The
1-3-1 is also the weakest zone for the fast break minded team
The other zone defenses provide a better set from which a team
can launch the outlet pass and fill the lanes.
Selecting
and Positioning of Personnel
Selection and placement of your personnel will either make or
break your match-up. Your point defender X1, will also be your
point guard, your ball handler and fast break leader. (Figure
1-2) This player will rec/the wing this defender must not allow
the wing to drive to middle. This defender now protects the high
post area by playing the passing lane to the high post. Should
the ball go inside, this defender must double team the post.
The
left wing, X2, is usually the other guard. This player must be
a decent rebounder as this will be your weak side rebounder. This
defender must be the better defender of X2 and X3. This defender
will usually have the other teams 2 guard or shooting guard. This
defender also has the responsibility of helping the corner defender
stop the drives to the middle.
X3,
the defender on the first attacker to the right of X1, is a position
for your weakest defender. The player also must be a good weak
side rebounder. This a good place to put a stronger scorer who
does not play great defense.
X4 is the reason you are playing the 1-3-1 match-up. This player
must be able to defend the inside. This defender will be the second
attacker on the right or left perimeter from X1 unless there is
a double high post, in which case this player would defend the
left high post. This player ideally will be second tallest player.
This player needs to be one of your better rebounders. This player
will help protect the insider from drives from the corners. This
is your defensive cornerback as this defender can see the whole
court.
X5,
is your offensive and defensive center. This should be your largest
player or best jumper. X5'2 primary defensive responsibility is
the opposition's center. If there are two low post attackers,
X5 takes the right side. This player should be your best rebounder.
This defender must also stop any penitration by the guards to
the middle.
