The thing is, that all of these numbers need to have our pace taken into account. Yes, we score the third-most points per game, but when you correct for our league-leading pace, we are tied for 9th/10th at 105.9 points per 100 possessions - only barely ahead of the league average of 105.4. And the team we're tied with? The Utah Jazz, who couldn't score 112 if you locked them in the gym alone because they have the #30 pace in the league. But on a per-possession basis, which is what really matters, their offense is just as good as ours - and neither is outstanding. Fully 11 teams, over a third of the league, are within half a point on either side of that measure, putting us at the top of the "middle of the pack", while the Warriors are 9 points better than us, the Thunder 6.8, etc.
So our offense is basically average. Our defense is a bit worse - 2.1 points per 100 possessions worse than average and #22 overall, but there's still a long way to fall - the Lakers are 5.1 points worse than average. The defense is bad, but not disastrous.
We need to improve both if we want to actually compete.
