The defensive system of an elite level basketball team is based on the execution of Rules and/or Concepts which are created by a team’s coaching staff to cover each situation which might occur during that team’s season; Rules and/or Concepts with which a casual [or, even, a die-hard] fan might not be familiar with already.

During this specific sequence:

Chris Bosh is X5, checking Tyson Chandler [C/O5].
Andrea Bargnani is X4, checking Boris Diaw [PF/O4].
Hedo Turkoglu is X3, checking Gerald Wallace [SF/O3]. 
DeMar DeRozan is X2, checking Stephen Jackson [OG/O2].
Jose Calderon is X1, checking Raymond Felton [PG/O1].

WHEN O1 MADE THE INITIAL LOW-POST ENTRY PASS TO O2 [RIGHT BLOCK] AND LAKER CUT TO THE WEAK SIDE OF THE FLOOR:

X1 was responsible for denying the Pass-back to O1 [as he cut through the lane to weak side of the floor [which is exactly what X1 did]. Once O1 got to the weak side, X1 was responsible for: i. Being outside of the lane on the weak side [to avoid an Illegal Defense Violation]; and, ii. Releasing Off his individual check [O1] to Zone Up against whichever opponents [i.e. 1, 2 or 2+] were located on the perimeter of the weak side.

X2 was responsible for defending against O2 in a 1-v-1 situation.

X3 was responsible for: i. Being outside of the lane on the weak side of the floor [to avoid an Illegal Defense Violation]; and, ii. Releasing Off his individual check [i.e. O3] to Zone Up against whichever opponents [i.e. 1, 2 or 2+] were located on the perimeter of the weak side.

X4 was responsible for: i. Being outside of the lane above the Free Throw Line [to avoid an Illegal Defense Violation]; and, ii. Releasing Off his individual check [i.e. O4] to Zone Up against whichever opponents [i.e. 1, 2 or 2+] were located on the perimeter above the Free Throw Line Extended [either on the weak or the strong side of the floor].

X5 was responsible for defending against O5 [located at the ball side elbow] in a 1-v-1 situation.

SPECIFIC RULES FOR O2 vs X2 POST-UP SITUATIONS vs MAN-2-MAN D

Since X2 is a frail 1st year player [20 yrs of age] who cannot defend successfully vs O2’s post-ups … based on a lack of guile and physical strength … X4 was responsible for Covering Down on the ball-handler to get the ball out of O2’s hands [in an effort to avoid the 1-v-1 isolation vs X2]. In general, there are three different techniques which a team can use to execute this specific Cover Down with X4, after the Post Entry Pass has already been made: I. Immediately, On The Initial Catch; II. Delayed, On The 1st Dribble; and, III. Late, on the 2+ Dribble. In this instance, the Raptors chose not to Cover Down Immediately, but to execute either Option II or III … which one exactly is unclear, given the physical movement of X4. All that’s known for certain is that X4 did not execute Option I.

AS X4 PREPARED TO INITIATE HIS COVER DOWN [either Option II or III vs O2]

X3 was responsible for Stepping-up Above The Free Throw Line Extended in order to maintain a Zoned Up position vs O4 [who moved above the Three Point Line] on the weak side of the floor [i.e. in order to avoid an Illegal Defense Violation].  

X1 was responsible for maintaining a Zoned Up position vs O1 [weak side FTLX] and O3 [weak side Corner].

X5 was responsble for: i. Denying an interior pass to O5 [who had cut to the weak side Block]; ii. Being within a step of O5 on the weak side of the floor [in order to avoid an Illegal Defense Violation], iii. Providing Help against a baseline drive by O2.

THE PASS FROM O2 TO O3 HAPPENED WHEN:

1. X4 shifted to the Left Elbow and waited for O2 to take his 1st dribble … which never came … in order to initiate Option I or II in his Cover Down vs O2.

2. X3 failed to communicate with X1 and X5 that he [i.e. X3] was Stepping-Up to defend the area of the floor above the Free Throw Line [i.e. where O4 was positioned] in unison with X4’s Cover Down; and,

3. X1 and X5 failed to: i. Recognize that X3 was Stepping-Up to defend that specific area of the floor and was no longer responsible for being Zoned Up on the weak side of the floor [i.e. vs O3 and O1]; and, then, ii. React quickly to the baseline basket cut which was beautifully executed by O3.  

SPECIFIC RULES FOR O2 vs X2 POST-UP SITUATIONS vs ZONE D

If the Raptors had shifted into their Zone Defense vs O2’s post-up, then their players would have been located in the following positions [in a 2-3 Zone]:

X2 - Left Baseline Defender … checking O2, in a 1-v-1 situation

X4 - Left Top Defender … at the Left Defensive Elbow

X1 - Right Top Defender … at the Right Elbow

X3 - Right Baseline Defender … at the Right Block

X5 - Middle Defender … at the Left Block

Since, X1 [i.e. Jose Calderon] did NOT step-up to the Right Elbow position and, instead, X3 Stepped-up to defend against X4, this indicates that the Raptors had not shifted into their Zone Defensive alignment during this sequence but were responsible for moving and reacting to O2’s post-up within the parameters of their Specific Man-2-Man Cover Down Rules.
