The NBA updates the record books each year, but not every season produces so many teams that stand out when peering through a historic lens.

From the San Antonio Spurs and Golden State Warriors to the Philadelphia 76ers, certain squads dotted each end of the overall spectrum. One franchise’s turnover issues resonated throughout the Association’s annals, while two others had no idea how to force those cough-ups. One organization from each conference served as a notable finisher on the offensive rebounding leaderboards.

Go ahead and familiarize yourself with the methodology behind our era-adjusted metrics if you must, then dive in to see some of the 2015-16 season’s most notable finishers.

Some of the Best and Worst Teams Ever

Even though the Oklahoma City Thunder played spoiler by knocking out the Spurs in the second round, it seemed as if the two teams with the West’s best records were destined to eventually meet up with one another for a rip-roaring seven-game clash. All year long, they were the class of the NBA, trouncing opponents while refusing to lose on their home floors.

Up until the end of the regular season, it seemed as if both the Spurs and Warriors could push past the 70-win barrier, with the latter challenging for the all-time supremacy they’d eventually earn with their 73rd victory.

By no means were the win totals fluky. Both the Spurs and Warriors asserted themselves as all-time greats on the Team Rating scale, as you can see below:

The methods behind the madness were strikingly different, though.

While the Dubs dominated on the scoring end and finished the year with the No. 3 adjusted offensive rating in NBA history (trailing only the 2003-04 Dallas Mavericks and 2004-05 Phoenix Suns), the Spurs thrived on defense. Only 12 teams have ever posted better adjusted defensive ratings, and Bill Russell played for five of them.

But this year wasn’t only marked by greatness.

The tank-happy Philadelphia 76ers stood out as well, once again for some rather ignominious reasons. While beating the Los Angeles Lakers for the season’s worst Team Rating, they finished ahead of only 19 historical squads—primarily because they had the 16th worst adjusted offensive rating in the record books.

Sticking With Golden State

If there’s one facet of the game that sees the Warriors stick out like a sore thumb, it’s shooting.

Led by Stephen Curry and Klay Thompson, they’re unbelievably adept at raining in deep jumpers, and it helps significantly that they’re an unselfish bunch willing to share the ball and turn down good shots for great ones. The system creates plenty of open looks for a deep stable of perimeter marksmen, but it also helps that someone can do this:

No one has ever shot this well relative to the rest of the league—a statement that applies to both Curry and Golden State as a whole.

Literally no one.

Prior to this season, the 2012-13 Miami Heat were the standard bearers for adjusted effective field-goal percentage. Then the Warriors came around and obliterated their record, topping those Heat by a gap as large as the one that separates Miami from the 1979-80 Los Angeles Lakers.

Those Lakers now rank No. 10.

Put another way: No team had ever posted an effective field-goal percentage at least 11.5 percent better than the league average. But even as the NBA’s overall shooting numbers continue to improve, the Warriors were more than 13.5 percent bette than the newest average.

Phoenix Butterfingers

This happened a lot:

The Phoenix Suns had no idea how to hang onto the basketball during their season from hell.

They turned the ball over 67 times more than any other team in the Association. They had six different players cough it up at least 100 times—particularly bad since only 122 did so throughout the entire league, meaning the average squad should have just four players on the list.

Only 26 teams have ever posted less impressive adjusted turnover percentages, and only three are from the last decade. Being this careless with the ball just isn’t supposed to happen in the modern era.

Offensive Rebounding Mentalities

For some teams, there’s no middle ground. Coaches don’t straddle the line between transition defense and second-chance opportunities, but instead commit wholeheartedly to one strategy at the expense of the other.

The Thunder were firmly on the latter end of the spectrum, often sending Enes Kanter, Steven Adams and Serge Ibaka to crash the offensive glass. Even Russell Westbrook got into the action, eschewing coverage of the opposing floor general en route to a staggering 145 offensive boards.

As a result, they narrowly edged out the 1994-95 Dallas Mavericks to post the best adjusted offensive rebounding percentage in the record books.

On the flip side, Atlanta Hawks head coach Mike Budenholzer basically spat on the idea of second-chance points. The Hawks couldn’t quite top the 2011-12 or 2012-13 Boston Celtics, but they posted a lower adjusted offensive rebounding percentage then everyone else.

It’s also worth noting that the Hawks’ extreme strategy is a fairly recent development. Each of the bottom 10 teams on the leaderboard took to the court no earlier than 2009-10.

Bright Spots in Minnesota

Andrew Wiggins. Karl Anthony-Towns. Zach LaVine.

There are plenty of reasons to get excited about the future of the Minnesota Timberwolves, and their ability to draw free-throw attempts is yet another. Young teams typically struggle to get to the charity stripe—learning to bait referees into whistles is a veteran trick—but they proved the exception.

Despite the prevalence of so much youthful exuberance, Minnesota posted the database’s No. 12 mark in adjusted free throws per field-goal attempt. Just imagine what this team could do with a little more experience.

Brooklyn Makes it Easy

Some teams take pride in contesting every field-goal attempt. They take it upon themselves to make the opposition truly earn each bucket, beating themselves up if they allow easy looks. They close out quickly and rotate properly, communicating constantly to ensure everyone fully understands the nuances of each defensive set.

Other teams…do none of these things.

The Brooklyn Nets were decent at forcing turnovers and crashing the defensive boards. They also refused to commit too many fouls.

But they had no idea how to prevent the other team from posting ridiculous shooting percentages. Only eight squads have ever posted worse adjusted effective field-goal percentages on the defensive end.

Thievery Practice Required

Both the Chicago Bulls and the New York Knicks couldn’t figure out how to force their opponents into mistakes. They failed to show quick hands on most possessions, didn’t understand how to disrupt passing lanes and never baited the opposition into seemingly unforced errors.

Now, each team registers among the worst ever for adjusted turnover percentage on defense:

At least they both have something to focus on as they spend the offseason trying to position themselves for significant improvement and future playoff berths.
