3-Out 2-In Motion Offense: Coaching the Two-Post System

If you are lucky enough to have two good post players, you should not spread them to the perimeter and waste them. The 3-out 2-in motion offense is built for exactly this team: three players on the perimeter, two players inside, and an offense that scores through high-low passing, inside-out reads, and relentless post screening. It is power basketball with motion principles underneath it.

What Is the 3-Out 2-In Motion Offense?

The alignment is three out, two in: a point guard and two wings on the perimeter, with two posts inside. Unlike a rigid set, it is a motion offense — the players read the defense and react within a structure rather than running scripted plays. The two posts give you interior scoring, offensive rebounding, and a constant high-low threat that pulls the defense apart.

Alignment and the Spacing Challenge

The hardest part of any two-post offense is spacing. Two bigs standing next to each other invite one defender to guard both and turn the lane into a crowd. The fix is a non-negotiable rule:

The Perimeter Rules

The three perimeter players run standard motion: pass and cut, fill, and drive-and-kick. With two bigs inside, guard penetration is especially dangerous because the defense is already occupied. When a guard drives:

• The near post ducks in or seals for a dump-off layup.
• The far post lifts or flashes to the open gap for a kick-out feed.
• The other guards relocate behind the drive for a swing pass and a clean look.

The Post Actions

Why It Works

• It maximizes two bigs. Instead of hiding a post in a corner, both are involved on every possession.
• It owns the offensive glass. Two players near the rim means second-chance points all night.
• High-low is efficient. Feeding over the top of a sealed defender produces layups and free throws.
• It punishes help defense. Help on a post leaves the other post or a shooter open inside-out.

Coaching Points

• Posts must move. A stationary post is a clogged lane. Duck in, flash, screen — never just stand.
• Feed with angles. Guards step to create a passing angle into the post; a flat feed gets deflected.
• Guard the spacing. The three perimeter players must stay wide. If the guards collapse, there is nowhere to kick the ball. (See spacing in basketball offense.)

Two bigs is a gift, but only if they move. Park them and you have a parking lot in the lane. Keep one high and one low, screen for each other, and let the guards drive into the mess — now two bigs is a weapon.

3-Out 2-In vs. Other Motion Alignments

If your two posts cannot both stay involved, or your guards need more room to drive, consider dropping to the 4-out 1-in motion offense and pulling one post to the perimeter. If you want pure spacing with no post, the 5-out motion offense is the answer. The 3-out 2-in is the right tool specifically when interior size and rebounding are your edge — lean into it, and pair it with the high-low offense reads.
