Switch-Everything Defense

Family: modern man-to-man. Switch every screen — on-ball, off-ball, all of them.

Why it's popular now

• Eliminates the chaos of help rotation on ball-screens
• Modern lineups have positional versatility — most NBA & high-major college teams have 5 switchable defenders
• Forces the offense out of its set play immediately

Principles

1. Switch every screen. No exceptions — even big-on-guard.
2. Late switch = death. Switches must be early and verbal ("SWITCH!").
3. Mismatch survival.

• Big on guard: drop deep, give up the pull-up, prevent the drive.
• Guard on big: front the post, expect the lob, weak-side help.

1. No catch-and-shoot 3s. Closeouts must be elite.
2. Scram switches — when a mismatch occurs, the next available defender re-switches to fix it.

Strengths

• Kills set-play teams
• Eliminates miscommunication on screens
• Frees up your scheme from complex coverage rules

Weaknesses (how to attack switch-everything)

• Mismatch hunting — set a screen with your worst-matched player. Attack the switch instantly (post-up the small, or iso the big).
• Slip screens — screener slips to rim before the switch happens.
• Ghost screens — fake screen + pop = uncontested 3 if defenders pre-switch.
• Spain PnR — back-screen on the dropping big's defender = unguarded roll.
• 5-out spacing — no help means switched mismatches play 1-on-1 in space.
• Re-screens — force them to switch twice in a possession; communication breaks.

Scout signals (they're switching everything if…)

• Bigs end up guarding guards on the perimeter
• No drop coverage on ball-screens
• Constant verbal communication on screens
• Fewer rotations / less help

Famous practitioners

• Brad Stevens / Joe Mazzulla (Celtics)
• Erik Spoelstra (Heat)
• Most modern NBA + most positionless college rosters

Verification notes (Claude)

• The Rockets (D'Antoni / Mike D'Antoni era, 2016–20) and Warriors (Kerr, "Hampton 5" / Death Lineup) are the canonical NBA switch-everything teams. Their famous personnel — P.J. Tucker, Trevor Ariza, Draymond Green, Andre Iguodala — were specifically built to enable switching 1-through-5.
• Brad Stevens / Joe Mazzulla Celtics and Erik Spoelstra Heat are correctly listed as modern practitioners; both lean heavily on switching with versatile wings (Tatum/Brown/Smart/White; Adebayo as a switchable 5).
• All listed counters (mismatch hunting, slip, ghost, Spain PnR, 5-out spacing, re-screens) are textbook and not in dispute.
• The Mike Prada book is real and recent (2022); coaches should easily find it.
