Miami Heat coach Erik Spoelstra knows how to ace an NBA test. He apparently knows how to copy one, too.

You know that new offensive approach everyone keeps raving about? The one that feels like it has already changed what’s possible for the Heat this season? Well, as innovative as it appears for them, it’s actually modeled off of the Memphis Grizzlies’ approach from last season. In fact, Spoelstra and his staff actually consulted with former Grizzlies assistant Noah LaRoche before installing the motion-based offense, per ESPN’s Brian Windhorst.

Memphis was a bulldozer with this approach last season—until suddenly it wasn’t. The Grizzlies skidded uncontrollably in the second half, eventually firing then-coach Taylor Jenkins (and LaRoche) with just nine games remaining in hopes of turning things around. Miami shouldn’t be as fearful of a free-fall, though, because the personnel seem much better suited to support this system.

Miami’s egalitarian approach emphasizes the depth of this roster and helps cover up the lack of a ball-dominant star.

While this new offensive system prioritizes pace and movement (of players and the ball), it also moves things away from mismatch-hunting and pick-and-roll play—staples in the modern league. In Memphis, it also meant fewer touches for star guard Ja Morant, who (unsurprisingly) wasn’t a big fan of that, and that may have sealed Jenkins’ fate.

The Heat have no obvious reason to worry about similar dissension within their ranks. They don’t have an offensive funnel like Morant. Tyler Herro comes closest, but while there will be an adjustment period whenever he makes it back from ankle surgery, you’d hope he sees the benefits of a motion offense that should help him find cleaner, easier looks at the basket.

“To make this work, you probably can’t have a ball-dominant star, and you probably need a pretty strong coach. Well, that’s what they have in Miami,” one scout told Windhorst. “They didn’t really have that in Memphis. We’ll see how it all works when Herro comes back.”

The Heat also have relentless workers who will keep the pedal floored, perimeter shooters willing (and able) to keep launching, and athletic play-finishers who can convert the scoring chances created by all of this activity. You can see how these players should fit the system. And if they manage to keep this up, this is how the whole becomes greater than the sum of its parts.

This isn’t the first time Spo has connected the dots in a way that allows his players to shatter expectations, but this is still one of his best coaching efforts to date. And to think, all it took was one glance over at someone else’s paper to figure things out.
