Coach Eric Bennaka's (@CoachBennaka) Underneath 4 when neither of the first two looks is there: the inbounds play turns into the flex continuity. The entry runs as always from the 1-4 flat line, 2's flex cut is covered, 1 curls up off 5's screen to the near elbow, and X1 recovers in time to take the jumper away. Now 5 slides out to the near corner and the offense is in flex spots: two elbows, two corners, one on the block. From there it is the pattern: the block cross screens for the corner, who flex cuts to the other block; the elbow down screens for the screener, who lifts to the elbow; the ball reverses and the same thing happens on the other side. Why it works: a defense that has survived the flex cut and the down screen once has to do it again from the other side with a different cutter, and every reversal gives the cutter a fresh angle. The read on every cut is the cutter's defender: trailing means feed the block, going under means wait for the down screen. The counter is built in, because the man whose cut was covered becomes the next screener. Common mistakes: reversing the ball before the flex screen is set, the corner cutting over the top, and the elbow forgetting the down screen so the screener never lifts. The set is Eric's; I picked it up from the doc he put together, which is linked on the first play in this set. The continuity itself is in our Flex post and Coach Daniel's breakdown, and both go deeper than I can here.
