In three out of the four games, they scored over 115 points, which is well over last season’s average of just 107.On top of that, in every game, they made an apparent effort to attempt more threes. They took over 30 three's in every game, the average from last season, and even took 52 three's in the first game against the Wizards.

Kemba Walker and Evan Fournier both averaged under 10 points per game while also shooting under 40% from the field and 30% from three.
