How often does the illegal defense get called? I have not been able to find any stats
that reference it?
Does anyone know of a statistical source that includes this stat?
Thanks!
Kurt

If you are speaking about the "3 seconds in
the key" rule: If you're on defense
and aren't
aggressively
guarding someone, you can't spend more than 3 seconds in the key
at a time. This is a relatively new rule in the NBA,
, and it was made because zone
defense is now legal in the NBA,
, but they wanted to have some restrictions on it (this rule). Before zone
defense was legal, it was also "illegal defense".
There are no statistical
sources out of the eBA System, and here is a new source too..

If you pretend to do an historical revision about the theme: before the 2001-2002 season, the
"illegal defense" guidelines were eliminated. A new defensive
three-second rule was put into place that prohibited a defensive player from remaining
in the lane for more than three consecutive seconds without closely guarding
an offensive player.
About this former and the new guidelines after 2001-2002 season, you can go to our Global
Basketball Directory.

This post RESUMES
the topic –
Illegal defense: A rather nebulous NBA
rule that was called irregularly. It's designed to prevent the use of the zone
defense, today legal in the NBA,
it was more like a 3-second
violation for the defense,
in which no defender can stay in the lane
for more than 3 seconds. If you were on defense and were not
aggressively guarding
someone, you could not spend more than 3
seconds in the key at a time.
The term Illegal defense has replaced zone
defense in NBA usage. The rule now in place, supported by guidelines, defines approved
coverage by defensive players and teams. Violations of these
rules and guidelines will be noted as Illegal Defense.
a. Illegal defenses which violate the rules and accepted guidelines set forth are not permitted in the NBA
.
b. When the offensive team is in its backcourt
with the ball, no illegal
defense violation may occur.
The illegal
defense guidelines needed to be eliminated because they have become problematic. They
are problematic for our fans, who don't understand the rule. They are problematic for the
officials, who admittedly have had difficulty administering the rule. And finally, the
teams have used the guidelines in a way that produces isolation Basketball.
Teams identify areas on the floor that they can use to their advantage in a given
offensive matchup and this produces a real sameness of play amongst a lot of the teams.
With isolation
Basketball, a lot of NBA
teams began standing around. There is little player movement, there is little ball
movement, and there is a decreasing amount of fast
break opportunities. These developments began with the misuse of the illegal defense
guidelines and therefore they needed to be eliminated. By eliminating them, the
desired result is to get a game that once again is based on passing, cutting, player
movement, and ball movement. A game that hopefully produces fast
break opportunities because that is the way our game should be played.
A defensive three-second violation that would prohibit a player on defense from being
in the lane for more than three seconds, except when the player is defending
an opponent in the lane area: When the illegal defense
guidelines were eliminated, the number one concern was that teams would take a bigger
player, like a Shaquille O'Neal, Theo Ratliff, Shawn Bradley, or Dikembe Mutombo, and
simply put him in the middle of the lane
to camp out and prohibit drives
to the basket and encourage low-percentage shots. In an effort to help alleviate that concern, the
defensive three-seconds violation was recommended. Prohibiting a player from being in the lane
for longer than three seconds will hopefully prevent a player from simply camping in the lane
for the entire possession.
This
summary resumes this topic and will be completed at "The Game" chapter of the eBA Basketball
Statistics Analysis System. Another Basketball stats topics you'll find at the Basketball Game
Discussions section of our eBA
Stats.com site.
