Drop Coverage (Ball-Screen Defense)
Family: ball-screen defensive scheme — the most common coverage in basketball.
How it works
- Big drops to the level of the rim (or short of the FT line) on the ball-screen.
- Guard fights over the screen and chases the ball-handler from behind.
- Weak-side help stays attached to shooters; tag the roller from the nail.
Why teams use it
- Protects the rim — no easy layups
- Keeps your bigs out of foul trouble
- Simple to teach
- Forces offenses to make tough mid-range pull-ups
Variations by depth
- Deep drop (at the rim) — protects against the lob, gives up pull-up
- Soft drop (at the FT line) — contests pull-up, gives up the lob
- High drop / show — big steps up, then recovers; hybrid
Strengths
- Eliminates rim attempts
- Limits 4-on-3 chaos that comes with hedges/blitzes
- Keeps your defense organized and rebounding-ready
Weaknesses (how to attack drop)
- Pull-up jumpers — elite-shooting guards (Curry, Lillard, ACAC equivalent) feast on drop.
- Pocket passes to the roller in the FT-line area
- Snake dribble — ball-handler dribbles back into the screen, gets to mid-range
- Re-screens — force the big to recover twice
- Spain PnR — back-screen on the dropping big = lob city
Scout signals (they're in drop if…)
- Big never leaves the paint on ball-screens
- Guard goes over the top, never under
- Pull-up jumpers are the main shot the offense gets
- Few defensive switches
Famous practitioners
- Most NBA teams default to drop with a rim-protecting 5
- Rudy Gobert (Jazz/Wolves) — quintessential drop big
- College programs with traditional centers

Verification notes (Claude)
- "Most common coverage in basketball" is true for the late-2010s NBA and remains common, but the league has shifted noticeably toward more switching and higher coverages since ~2022 (especially in the playoffs vs elite shooting guards). Coaches should treat this file as accurate but understand the NBA mix has moved.
- The Spain PnR / back-screen counter to drop is well-documented; the file's framing ("lob city") is accurate.
- I could not verify a single specific Cleaning the Glass article URL on drop coverage in this session (the site is partly paywalled); the site is the strongest written source on this topic but does not surface clean public URLs for individual concepts.
