OVERVIEW
This video breaks down two 3-on-3 live drills that Summit Jaguars uses to install their man-to-man defensive system, with game film examples showing the concepts translating to real possessions, including a state semifinal and state championship game.
DRILL 1: THREE-ON-THREE BASELINE DRIVE
The ball starts with a player driving baseline, and the defense is coached to give heavy help on the ball. The core teaching points:
- On the catch, the on-ball defender should immediately take away both driving gaps so the offensive player never sees a clean lane.
- Defenders are taught a “foot to foot” positioning cue — staying tight to the hip of the ball handler.
- Help defenders react to the baseline drive, sink low, then sprint out to close out with high hands.
- Defenders should be closing out under control, aiming for a blockout on any shot.
- Coverage priority is emphasized: the first spot that must be covered is the baseline, and the second spot is under the rim. If a mistake happens (like the wrong player taking baseline), the next defender should react and rotate to the next open spot rather than freezing.
- The larger goal is turning the ball handler into a passer, then swarming/walling up to force a tough shot.
- Game film from a state semifinal against Colleen Ellison is used to show these exact rotations happening live, including a defensive breakdown where the correct rotation still bailed the team out.
DRILL 2: THREE-ON-THREE JUMP TO THE BALL
This drill emphasizes closeouts and communication, tied to the program’s “TOUGH” acronym — Through Our Unity Greatness Happens — the philosophy that one defender guards the ball while four others are always helping.
Key coaching points:
- The goal is to create “long closeouts” by jumping to the ball and communicating, rather than reacting late.
- Defenders should avoid running directly at their assigned man (which risks getting screened or beat) and instead run through the gap to their help spot.
- Baseline defenders are coached to hold their position until the defender rotating down verbally confirms “I’ve got baseline,” then sprint up into the gap.
- Body positioning cue: butt to the rim, chest to the ball, staying reactive to baseline drives.
- Because it’s non-contact, the drill is used purely to sharpen technique — closeout angles, communication timing, and helping without over-helping (getting caught on screens or gambling for steals instead of playing the gap).
- Game film from a state championship game shows this drill in action late in the first half, with the defense successfully closing out on a series of down-screen actions and forcing a bad pass, though one clip shows a defender chasing his man instead of playing the gap and missing a steal opportunity.
KEY TAKEAWAY FOR COACHES
Both drills are built around the same core defensive principles: aggressive baseline containment, clearly defined rotation priorities, verbal communication on closeouts, and disciplined gap play over chasing individual matchups. The “TOUGH” philosophy reinforces that this is a five-man, unified defensive system rather than isolated man-to-man matchups.
