Denver was able to have the league's 5th best offense despite being a bad 3-point shooting team. They were 20th in makes per game at 6.4 on just 34.3% shooting (even the Raptors were better than this, same percentage more makes).
Denver also doesn't have any players that one would consider elite offensively... or even any guys that excel in halfcourt isolation.
So how the hell was their offense so good? By pushing the tempo (2nd in pace) and attacking the rim in the halfcourt set. Look at the shot chart for their best 5 man unit (Lawson-Iggy-Gallo-Faried-Koufos).
More than HALF (174/300) of their shot attempts as a unit came inside the paint, which allowed them to shoot 51.7% from the field as a unit. This is ridiculously efficient.
I'd argue that we have more offensive talent than that Nuggets team, better defensive players and either equal or better rebounding. We also have the athleticism to push the pace offensively while still playing great defense (despite their pace Denver was still 11th in defense). So why the hell isn't it happening?
