This is what Jordan said about the post:
Examining some of the recent trends in offensive rebounding concepts.
The weak side flood was made famous by Illinois coach Brad Underwood.
The triangle concept is a more traditional approach.
The abandonment concept is a new trend that many colleges and NBA teams like the Nets, Hawks, Spurs and Warriors have implemented.
The top back concept. Players above the free throw line extended when the shot is taken are getting back on defense. Players below the free throw line extended are crashing the offensive glass.
Red: Opposite Inside-player from the strong side of the shot circles under the rim to the weak side of the shot.
Yellow: Weakside Flood-next two or three players flood the middle and weakside of the floor.
PG retreats for transition defense.
PG and shooter retreat back on defense.
The other three players fill the strong side block, weak side block and middle lane to form a triangle.
Sending all 5 players back on defense or allowing best rebounder to crash the offensive glass while the other 4 players get back on defense after a shot.
