Scram Switch

One-line: A defensive call where a help defender re-switches to fix a mismatch created by an earlier switch.

How it works

1. Ball-screen happens. Defense switches — now the big is on the guard, guard is on the big.
2. The big-on-guard mismatch is bad (drive coming).
3. Scram: the next-closest defender (often the weak-side big or wing) leaves his man and switches WITH the mismatched big — eating the original switch.
4. Now the big is on a different perimeter player, and the original guard's defender (who took the big) is restored to a small.

Why it works

• Eliminates persistent mismatches without having to play them out
• Allows you to switch ball-screens without giving up a long mismatch possession
• The "fix-it" call inside switch-everything

When to use

• Anytime a switch creates a glaring mismatch you can't live with
• Especially vs teams that hunt mismatches off ball-screens

Defense rules

• Scram must be early — within 2 seconds of the switch
• The scram-help defender must communicate ("SCRAM!")
• The new mismatch (small on a non-shooter) must be acceptable

How offenses attack scram

• Throw to the original mismatch immediately before scram can happen
• Re-screen to force another switch
• Scram into a back-screen — when the scram defender leaves his man, screen him

Verification notes (Claude)

• "Scram switch" is genuinely modern NBA terminology (popularized roughly 2017–2020 in public discourse, though the concept of help-side re-switching predates the term). I could not source a single canonical "first use" of the term in this session.
• Erik Spoelstra (Heat) and Brad Stevens / Joe Mazzulla (Celtics) are the most-cited public examples; Steve Kerr's Warriors also use it. The file's framing is consistent with this.
• The "scram into a back-screen" counter is a real, documented offensive answer (Spurs / Heat film) — not fabricated.
• This concept is harder to verify than the others because it lives mostly in NBA staff vocabulary and YouTube film breakdowns, not in books or named clinic systems.
