What it is
- The Flex Offense is one of the great continuity offenses in basketball, first popularized by Carroll Williams and later adopted by dozens of college and high school programs.
Why it matters
- It is built on a repeating two-action pattern — a baseline screen followed by a back screen — that cycles all five players through scoring opportunities.
- The genius of Flex is that it is genuinely hard to scout: the same two actions look different based on how the defense plays them, and the offense simply adjusts its cuts accordingly.
How it works
- Action 1: The Flex Cut (Baseline Screen)
- The ball is on one elbow (or wing). The opposite corner player sets a baseline screen for the same-side corner player.
- The same-side corner player uses the baseline screen to cut across the lane to the opposite block — this is the Flex Cut.
- The ball-handler at the elbow looks to feed the Flex cutter for a layup or short jump shot.
- If the Flex cut is not open, the ball is swung to the top.
