Missed jumpshots = missed jumpshots.
It's only grating to y'all because the jumpshots that are being missed are taken from a few more feet out.
Regardless of that, if y'all had watched the Rockets play this season, you'd see this is how their games typically flow. They make it a defensive battle, and because they don't really have any structure on offense, it ends up fukking up the rhythm of the game, dragging the opposing team down in the process.
Pretty much in all of OKC's last 10 games, they had no trouble generating offense on a high level. This game is merely an outlier to how they typically play. It happens. The season is 82 games long. No team is going be efficient in every game. This has always been the case and it always will be the case.
