Detroit Golf Club just spent $16.1 million to make you think harder about where you're aiming.
The club's tournament course — a 1916 Donald Ross design — came out of a full restoration by architect Tyler Rae in time to host the Rocket Classic this past weekend. It played as a par 70 at 7,328 yards, with two reachable par 5s converted into long par 4s. Bunkers were deepened and put back roughly where Ross originally drew them. Michael Thorbjornsen won at 18 under for his first Tour title, closing with a 63 and a 26-footer on the last.
Winning scores there had averaged around 22 under. This year, 18. Which reads like the restoration bit hard — and that read is wrong.
Thorbjornsen's 72-hole total was 262. That is the identical raw score to Tony Finau's 2022 tournament record. The winning number "fell" four shots because two par 5s became par 4s, and for no other reason. Par is a label. The shots are the truth.
So the restoration didn't punish scores. It punished positions — which was the stated point of putting that bunkering back. Not to make the fairways harder to find, but to make which side of the fairway you're on matter as much as finding it.
Sit with that. Sixteen million dollars on a golf course whose primary opinion is about your target. Not your swing. Your target.

The two skills golf refuses to teach together
I had a student a couple of seasons back — I'll call him Dan, a 14 handicap who hit the ball better than he scored. He came in convinced he needed a swing fix. We didn't touch his swing for the first three weeks. We looked at where he was aiming.
Dan aimed at the flag. Every time. Tucked back-left over a bunker, four paces from the water, didn't matter — that's where the flag was, so that's where he pointed. And his miss was two-sided, maybe 25 yards each way with an 8-iron, which he had never measured and could not have told you if I'd asked. So roughly half his approach shots were being aimed into trouble before he ever took the club back.
That wasn't a swing problem. That was an un-audited pattern meeting an unearned target.
Golf teaches those two things in separate departments. Technique is a lesson; course management is a podcast. Nobody hands you the sentence that welds them together — but somebody said it out loud last month, about the kid who beat Scottie Scheffler at the 3M Open. Describing Jackson Koivun to reporters, his former Auburn teammate Josiah Gilbert put it this way:
"His dispersion is second to none, like he does not hit bad shots — he picks some of the safest targets out of anyone out there."
Read it again, because there are two separate claims in there. He knows how wide his pattern is. And he aims accordingly. Those are different skills, and the second one is free.
The 10-ball audit
Before you can aim a pattern, you have to see it. Most golfers never have. So measure it — one range session, fifteen minutes:
- One club. A 7- or 8-iron. Something you'll actually hit into greens.
- One target. A flag, a marker, a specific yardage plate. Not "out there."
- Ten shots. Your normal pre-shot routine, normal pace. No do-overs, no "that one doesn't count."
- Photograph all ten. Phone out, one picture of where every ball finished. Not your best one — all ten.
Now measure the width: leftmost ball to rightmost ball. That number is your cone.
One coaching note that matters more than it sounds like it should: while you're hitting those ten, keep your attention on the target, not on your swing. Gabriele Wulf and Rebecca Lewthwaite's work on attentional focus is about as settled as motor learning research gets — an external focus produces better accuracy and better retention than an internal one. Spend the audit monitoring your positions and you won't measure your golf swing. You'll measure a self-conscious version of it.
In my experience with mid-handicap golfers, a 7-iron cone lands somewhere around 30 to 40 yards wide. Almost nobody guesses that high before they measure it, and almost nobody argues with it after.
Your cone isn't random — that's the good news
The reason I like this drill is that the number it produces isn't mystical. The width of your pattern comes from three measurable things:
- Face angle at impact starts the ball — roughly 80% of your starting direction. This is the single biggest contributor to how far left or right the ball begins.
- Path relative to that face bends it. The mismatch between where the club is traveling and where the face points is what curves the shot.
- Low point decides your contact. Hit the ground behind the ball and you lose compression and distance control, which stretches the pattern long-and-short instead of left-and-right.
That's it. Three variables, all of them measurable, all of them changeable. Which means your cone has a width today and a different width in six months if somebody works on the right one. That's the technique half of the job, and it takes time.
The strategy half takes about four seconds per shot and starts on your next round.
The rule: aim so your whole cone is playable
Here it is, and it's the entire article in one line:
Aim so your entire pattern is playable — not so your best shot is perfect.
When you aim at a flag tucked five paces from water, you are not aiming your shot. You're aiming your best shot, and quietly betting that the other nine in the cone are survivable. They usually aren't. That's what short-siding is: a bet you didn't know you were making.
Run Dan's math instead. If your 8-iron cone is 25 yards each way and the left edge of that green has a bunker with water behind it, aiming at the flag puts a third of your realistic outcomes somewhere bogey is the good result. Move your aim 15 yards right, into the fat of the green, and the worst shot in your cone becomes a 40-foot putt. You didn't change your swing. You changed the consequence of your miss.
This isn't a hunch. It's the same conclusion Mark Broadie reached in Every Shot Counts after working through millions of shots: aiming at the middle of the green outperforms firing at tucked pins for the overwhelming majority of golfers, because the misses cost far more than the makes gain. Amateurs consistently underestimate how wide their own dispersion is, which is exactly why the flag looks like a reasonable target when it isn't.
It's also, more or less, how last weekend was won. Thorbjornsen led the entire field in greens in regulation — he missed nine greens in four rounds, and one on Sunday — and ranked fourth in strokes gained off the tee. He didn't overpower a restored Ross course. He kept ending up in the places it rewarded.
Detroit Golf Club charged itself sixteen million dollars to say this in bunker form: being in the fairway isn't the whole answer, because the golf course has an opinion about where in the fairway. Your home course has that opinion too. You've just never asked it.
The honest split
I want to be straight about which half of this you can do alone.
Aiming your cone correctly is free. No lesson, no launch monitor, no new swing thought. Run the audit, learn your number, and start picking targets that respect it. Most golfers I've done this with drop a couple of shots a round inside a month — not because they got better, but because they stopped donating strokes to targets they were never entitled to.
Narrowing the cone is coaching work. Figuring out which of the three variables is actually driving your width takes diagnosis, because a face problem and a path problem have opposite fixes and guessing wrong makes it worse. That's the part I do.
But do the free half first. Ten balls, one target, one photo.
