One of the biggest mistakes NBA teams routinely make is building for the past instead of the present. The Houston Rockets are notorious offenders. Their micro-ball lineup would have worked wonders against the Golden State Warriors... but the Warriors were no longer their competition for the championship. As we later found out, the Lakers were, and Houston's gambit failed because of how ill-equipped it was for Anthony Davis' size.
Quietly, the Clippers fell for the same fallacy. They looked at the league that the Warriors left in their wake and decided that traditional positional roles were meaningless. They assumed that Kawhi Leonard, a small forward, could function as a primary ball-handler, and that center defense was a luxury as long as they were strong enough at the point of attack. It wasn't just that their two best players were wings. Functionally, even their non-wings were, essentially, wings. Patrick Beverley and JaMychal Green functioned as switchable shooters, not traditional archetypes for their positions. At the trade deadline, they cashed in their only chip (their own 2020 first-round pick) for another wing in Marcus Morris rather than a point guard or a center.
