That's interesting comment from your son but it seems to assume a binary choice of going for the pin or playing completely safe. From the correct angle he can choose to play somewhere in between. His chances of success of sinking a 15 ft putt are surely better than sinking a 30 ft putt ?
It's not really Jeff's son's take: that's what Lou has said all along as well: people play more conservatively when they have the "wrong" angle, which is actually roughly where they SHOULD play from any angle, but they'll typically aim closer from the "right" angle and short-side themselves or whatnot.
I'm surprised that nobody has tried to show that "angles matter" by looking at the stats and showing something like this… Let's say that from 150 yards in the fairway a class of player averages 3.12 shots from the "bad" angle and 3.15 shots from the "good" angle (so, a pretty good player). Those are so close it's basically a wash, but how they get those averages might be something like this, out of 1000 times played:
"Bad" Angle (4.12): 1 eagle, 111 birdies, 667 pars, 218 bogeys, and 3 doubles.
"Good" Angle (4.15): 3 eagles, 129 birdies, 592 pars, 265 bogeys, and 11 doubles.
That might show "angles matter" a little… because the scoring spread changes. One location results in more under-par scores but also more over-par scores with fewer pars. But then I'd counter to point out that these stats are derived only from shots hit from the fairway, so if the "better" side of the fairway also has a fairway bunker over there, then that is going to massively affect the scoring, and that you shouldn't play for that angle you should play for safety first… and so on. Which is what Kyle and I have been talking about, ultimately.
That's why the ultimate target is often still basically the same on the green (or should be) regardless of where you're playing from… (as long as the ball isn't rolling, and any other rare exceptions).
But you would have at least shown that even though the numbers can work out the same, the actual resulting angle
might matter in that sense. It'd be looking at it a little too closely, and not seeing the bigger picture, but it'd still speak to the point a bit.
