Basketball defensive systems:
0:03
1-3-1 defensive system.
0:07
In this defense, player 1 is the
0:10
point guard, 2 and 3 are the wings, 5 is
0:14
the center, and 4 is the baseline player. Okay,
0:18
now let's look at the
0:22
basic movement patterns in this system. The
0:24
ball goes to the offensive 2, and our 3 moves out to
0:31
starts moving to the side where
0:33
the ball is, getting closer to the
0:37
The defensive 2 starts crowding the
0:40
middle, and 1 moves as well, as do
0:46
Now the ball is in the corner, and 4 moves
0:49
to guard the corner player.
0:51
Our 2 would replace his position,
0:54
ending up practically under the basket, and
0:57
we clearly see another 1-3-1.
1:02
Now let's go to the other side, and it would be
1:05
practically a mirror image,
1:06
but exactly the same.
1:09
2 is the one who now moves out to guard the player
1:14
in the offensive 3 position.
1:16
4 starts moving towards
1:19
a corner, and 3 is the one who now
1:21
starts crowding the inside
1:23
so that 5 and 1 move a
1:26
little to the side. Where is the
1:30
now? Here, finally, the ball passes to the
1:34
offensive player 4. Similarly, the 4 begins
1:37
to run towards the corner.
1:40
The 2 also makes a short run
1:43
from where the ball is. The 5 is in
1:45
the middle, and the 13 is
1:47
now positioned right under the basket,
1:50
marking his position.
1:55
Now we see how each player on the
1:58
team applying this 1-3-1 system
2:02
marks their position and where they have to
2:05
move. Basically, we see the
2:07
colors that distinguish them and
2:09
the area or zone that each one would occupy.
2:14
Some relevant aspects of this
2:17
system are that it is a good zone defense
2:20
for working on defensive intensity and
2:23
coordination among the five
2:24
players. Another is that it is a demanding defense,
2:27
of course, so the players
2:30
must be in a certain physical condition. The
2:33
players must keep their
2:35
arms open and raised, occupying their
2:37
designated space or zone. And another is that it
2:40
greatly facilitates learning
2:42
communication in defense, as it is a
2:43
very important factor in this defense, and well, of course,
2:52
1-2-2 defensive system.
2:57
Very good. Here the ball is in
3:00
the offensive position of player 1
3:03
inside. From the Y-axis, we see a clear 1-2-2
3:08
defensive system. The
3:11
ball is passed to the offensive 2 at a 45-degree angle. Here we see
3:15
that in this case, our 2 is guarding the
3:18
offensive 2. Our 5 starts
3:20
managing the zone, and our 4 slowly
3:22
begins to move to the corner, which is key
3:25
for this zone, just like for all
3:27
zones. Arms are active all the time to
3:30
occupy more space and make the
3:32
defensive zones smaller. The
3:34
ball is now in the corner, and here we see
3:37
a clear 1-2-2. If we have, of course, the
3:40
ball as a reference point, the main
3:43
communicators with the ball in the corner are
3:45
the 5 and the 3. We see a movement by
3:48
the 2 who approaches, trying to
3:52
create almost a 1-2-on-1.
3:56
If we go to the other side, the 13 is
3:58
now doing the direct marking. The
4:01
5 dribbles a little towards the
4:04
corner, and the 1 stays there a little,
4:08
sliding to our left. The
4:12
4 positions himself a little below the
4:15
basket, and the 2 makes a small movement. The
4:17
main communicators are the 4 and, of
4:22
Here we basically observe how
4:25
the 5... The player who plays
4:28
direct marking is number 3, who also moves out a bit to
4:31
mark the player. Number 4 is fully positioned
4:33
under the basket. Number 2 slides slightly
4:37
towards the center, and number 1 stays
4:40
somewhat in his zone. Basically, a mirror image is created
4:44
the previous plays on the
4:50
Here we can observe how
4:53
each area that each player must cover is marked and designated in
5:00
defensive system, with each player marking their
5:07
Some of the strengths of this
5:10
system are that it is a good defense
5:12
against a team with good outside shooting
5:14
but without a very strong inside game.
5:19
pressure on the ball on the perimeter,
5:22
especially on the sides, offering many
5:25
second-on-one opportunities. It is also
5:30
masking both zone and
5:32
man-to-man defenses. The
5:35
2-1-2 defensive system: In this system,
5:39
we find the power forward and small forward at the back, the center (number
5:45
5) and the point guard (number 1) in the center, and the point guard
5:49
and shooting guard at the front. Now
5:52
we see some of the movements that are
5:58
As we can see, the attacker is
6:01
number 2. From the offensive team, player
6:05
2 of our team goes out to mark the ball. If you
6:11
212 base remains and doesn't move; it has the
6:16
same parameters. In the same way,
6:18
when the attacker passes to the next
6:24
4 is the one who now moves to the
6:26
corner. When the ball reaches the
6:29
corner with the offensive player, player 2 makes a
6:31
run, trying to create a 1-2-
6:33
on-1 situation, and player 13 is the one who now
6:36
maintains communication and positioning himself
6:40
low, just long enough.
6:44
Now let's go to the other side, about 45 degrees, and
6:52
212 position. Player 1 is the one who goes out to mark player
6:55
3. Player 3 moves a little towards a corner.
6:58
We see the same alignment of the system, and
7:02
now player 40 starts to position himself
7:04
under the basket. Players 5 and 2 simply
7:14
have already pointed out in the
7:15
other systems. Here, it is simply
7:18
a mirror image compared to the
7:21
opposite side. When the ball reaches
7:23
position 5 of the offensive player,
7:27
the defensive players simply
7:31
move. Player 1 is the one who goes out and
7:33
dribbles to mark the ball. The one who moves around
7:35
a bit and keeps marking
7:38
the 3, the 5 moves around as well, the 4 is the one
7:42
who positions himself right under the
7:44
basket, he's the one who
7:46
manages that. The 2 also makes a
7:49
movement, and practically they are the ones who
7:51
have the communication.
7:53
Now, well, we see here again, as
7:56
in the other systems,
7:58
clearly the zones or spaces that
8:01
each player has to mark within
8:04
The three, the two at the back, sorry,
8:07
the 3 and the 4, are the ones who mark there the
8:10
green area. The 5 marks the whole center,
8:12
marking, pointing to that circle.
8:15
1 and 2 are in front of this
8:18
system. We see there clearly in
8:21
blue the area or space that they have to
8:25
cover when performing this system.
8:31
As in all systems, it is a system
8:33
that requires a lot of communication between
8:35
the players and a certain, and
8:38
mostly, physical capacity in the
8:40
players, and mainly skill,
8:44
both coordination and communication. That
8:48
would be all from me. Thank you very much and
