For a minute, in Miami, his shot was nice.

This kind of abrupt drop-off does happen from time to time, but not often. Going into the season, Basketball-Reference.com’s simple projections called for James to make 36.2 percent of his 3-pointers, a mark he’s currently missing by 8.6 percentage points. Since the NBA introduced the 3-pointer in 1979-80, 822 players have entered a season with as large a sample of prior 3-point shots2 as James while also firing off as many attempts during the season being projected; only 10 (1.2 percent) have missed their expected mark by a wider margin than James’s current shortfall.
Granted, one of those players is Atlanta’s Kyle Korver, who has fallen 8.8 percentage points shy of his projection this season. (Fun note: Korver’s definition of a “disappointing” 3-point percentage is still 3.4 points higher than league average.) Historically speaking, we’d expect only one NBA player to experience this type of shooting slump once every two or three seasons, but the 3-pointer’s ever-skyrocketing frequency gives contemporary players more chances to join this sample — and to underperform their expectations — than players of a generation ago.
Still, a dip like James’s remains pretty rare:
So what’s causing James’s sudden regression behind the arc? It certainly isn’t an increase in long-range volume. His 3-pointers make up a smaller share of his total shots now than they did a season ago, bringing that proportion more in line with what it was in 2012-13, when James knocked down a career-best 40.6 percent of his 3s. Nor is it a matter of location. We would actually expect James’s conversion rate to be marginally better this year based on the distribution of his 3-point attempts by zone; he’s shooting slightly more of the shorter, easier variety of 3s that reside in each corner of the court.
Amazingly, the culprit for James’s declining percentage doesn’t even appear to be the circumstances under which he’s had to shoot.
Last season, James had the benefit of an assist on only 46.7 percent of his 3-point baskets; this year, that rate is much higher, at 62.1 percent.3 Somewhat relatedly, James also shot more pull-up 3s last season — you know, the onesonly Steph Curry can turn into a workable offensive strategy. This year, he’s shifted about 11 percentage points’ worth of those4 into 3s of the much easier catch-and-shoot variety. And a smaller share of James’s 3-point attempts this season have come in difficult shot clock territory — categoriesmarked by NBA.com as “Late” or “Very Late” — or against tough defensive pressure — classified by SportVU’s tracking cameras as “Tight” or “Very Tight” — than last season.
In other words, practically every statistical indicator says James should be shooting the ball better this year, not worse. An already improbable downturn is made all the more baffling by the lack of a logical explanation — with all of our data and technology, we’re supposed to be able to dissect and diagnose cases like this. James quantifiably has more space and more time, and he even says he feels significantly better than he did last season, but the shots are simply not falling.
James doesn’t seem to have any answers, either. “I could care less about what I shoot from the 3,” he said when asked about his abysmal 3-point shooting by the Cleveland Plain Dealer earlier this month. “It’s not my game … Like I tell you guys at the end of my career they’re not going to say LeBron was a great 3-point shooter. I’m going to continue to take them. I work on them. If they go in, fine, if not I’ll live in the paint. So I’m not a 3-point shooter, I never will be a 3-point shooter. If I shoot it well, cool, but that doesn’t define my game, shooting 3s.”
Somehow, James has managed to make that formula work for him. Cleveland ranks fourth in offensive rating, and LeBron has individually maintained the league’s third-best offensive Real Plus-Minus despite the wayward perimeter shooting. Perhaps that shouldn’t surprise us much — after all, a younger James’s production was off the charts before he ever developed a credible long-range jumper. At the very least, it suggests the Cavs might be able to capture another Eastern Conference crown even if James doesn’t miraculously regain his touch from the outside. But as far as statistical puzzlers go, James’s inexplicable shooting collapse is one for the history books. Even in the modern age of advanced basketball metrics, sometimes we have to deploy the analytic equivalent of a shruggie.
