The Art of Making Shooters Miss
Analyzing who actually contests shots and makes opponents miss using NBA tracking data.
I've got NBA shot tracking data from the 2014-15 season. Who are the best defenders based on this data?
Let me query the shot logs to find defenders who force the lowest opponent field goal percentage. I'll filter for players who contested at least 300 shots to ensure statistical significance.
Tony Allen stands out at 35.5% opponent FG - nearly 5 percentage points better than the next defender. They don't call him "The Grindfather" for nothing. Andre Roberson and Andrew Bogut round out the top 3. Interestingly, Stephen Curry appears on this list at 39.7% - not just an offensive threat, but a capable defender too.
Do these defenders have different specialties? Like perimeter vs paint defense?
Great question. Let me break down their opponent FG% by shot type - 3-pointers vs 2-pointers.
The profiles are completely different. Draymond Green is elite on the perimeter - holding opponents to just 25.3% on threes - but gives up 43.8% on twos. He's a switchable defender who closes out hard. Tony Allen is excellent at both (28.9% on threes, 39.2% on twos). Meanwhile, DeAndre Jordan struggles more with 37.3% on threes and 49.2% on twos - he's a rim protector who gets pulled out of position on switches.
Wait, shouldn't tight defense always lead to lower shooting percentages?
You'd think so, but the data tells a counterintuitive story.
The paradox: contested shots (2-4 feet) have the HIGHEST FG% at 47%, while "open" shots (4-6 feet) have the lowest at 43.3%. Why? Shot selection. Tight defense mostly happens at the rim - layups and dunks that convert at high rates even when contested. Open shots tend to be mid-range jumpers, historically the least efficient shot in basketball. This is why raw "contests" don't tell the whole defensive story.
How does pressure affect shooting? Like in clutch moments?
Let me look at FG% by game situation in the 4th quarter.
The pressure effect is real. FG% holds steady around 45% through most of the game, but drops to 38% in the final 30 seconds of Q4. That's a 7-8 percentage point swing when the game is on the line. Increased defensive intensity, fatigue, and pure mental pressure all contribute.
So who actually thrives in those clutch moments?
Let me find the players who perform best in the final 2 minutes of the 4th quarter.
DeMarcus Cousins leads at 71.4% - he was dominant in the post when games got tight. Goran Dragic and Anthony Davis also crack 67%+. The common thread? These are players who attack the rim rather than settling for contested jumpers. When pressure mounts, going to the basket beats pulling up from three.
