Flex Offense Essentials: Basic Continuity and Counters to Net Easy Baskets

The Flex Offense has been a popular offensive system at the high school and college levels of basketball for many decades. By using efficient spacing, lots of flaring action, and flex screens, plus constant movement on the offensive end, the Flex can be extremely effective, especially if executed properly.

In this week’s team concepts feature, Elizabethtown men’s basketball coach Bob Schlosser reveals his twist on the Flex, which eliminates the downscreen to create some high-percentage shots. Follow along as Coach Schlosser runs through the basic continuity before getting into counter plays to net easy baskets.

Basic Continuity

We start things off with a 2-out and 3-in alignment and make five passes before shooting a layup while running the flex pattern.

Keys: Whenever catching the ball, get into triple threat position. When the cutter is coming off the flex screen, he must show his hands and set his man up. When the screener is setting the screen, he must step out a bit. Players must also ball fake and shot fake constantly. Also, but quick, but don’t hurry.

In Schlosser’s Flex Offense, the team doesn’t down screen. Instead, when a player up top catches the ball on the cross pass, the squad feels he has room to pull through before the flex cut comes or he can pass to the corner and make that jumper where it’s not clogged.



First, we’ll run a backdoor play to end the first counter. Without the down screen, we have opened up an entire side of the floor. If this post/low block player is denied, he can run backdoor.

Let’s take a look at the action involved to set this up. Initially, a pass is made from guard to guard up top, then there’s a flex cut by the opposite corner player along the baseline using a low block screen provided by the low block player. After setting the screen, the screener cuts up to the elbow and then cuts backdoor immediately. He can also step out and to the near corner, replacing the former corner player (who steps up top to receive the pass across). We can then get right back into our flex continuity from here.

Meanwhile, the option is also there for a pass off the elbow. When we pass off the elbow, look to stagger screen away. If we pass the ball to the corner, we are going to stagger screen and then get right back into our flex spots if we aren’t able to enter the ball into the post.



With “Go”, when the guard makes a pass across for the other guard, we have the options for a shot, pull through/rip through, or entry to the inside. We run the “Go” if a defender cheats on the cut as the pass is made. This frees up a player to catch the ball up top, hit an open jumper, or rip through if his man closes out.

Duck In

Finally, in “Duck In”, as the ball is passed from the top right to top left, the right side corner player sprints baseline, comes off a low block screen from his low block teammate, then cuts right off the shoulder of his low block screener and sprints to the opposite low block and faces the ball looking for the pass.

Meanwhile, after setting the screen, the screener ducks into the paint, with both hands reaching out, looking for the pass down low and a quick layup. This can be beneficial if the defense switches. The low block screener can now receive an inside pass off the duck in and layup. It’s key that guys here read the defense in switching or non-switching situations.

Great stuff!! Thanks!!! Will use these counters and run a back screen from time to time for fading guard by screening post.
