JSF Nanterre Flex Transition Offense

Now we are going to check a Flex Transition Offense used by JSF Nanterre that is played by the french to seek the 5 at the low post or to seek the 3 at the top of the key.

From the set showed in the picture 4 sets a
ballscreen for 1 who dribbles to the left side
wing. 3 sets a cross screen for 5 who slides
to the left low post. 3 pops to the top of the
key being downscreened by 4.

1 can pass to 5 at the left low post or to 3 at
the top of the key.
If 3 receives the ball at the top, then 4 sets a
ballscreen for him.
