This Spurs /Thunder series has to be up there.

I don't know, but I'm guessing it didn't go 7.

From a tweet in that article:

---

The combined margin of victory in this series (102 points) is the largest through 5 games of a conference finals since 1985 LAL-DEN (105).

That LAL-DEN series only went 5 games.

Largest sum of victory margins, points:
134 by the 2009 Atlanta Hawks and Miami Heat (7-game Prelim).

The 2009 NBA Playoffs also had a series between the Nuggets and Hornets that had a combined margin of victory of 125 points. That included an NBA playoff record-tying 58 point win for the Nuggets in Game 4.

The other 58 point win was in 1956, and the winning team lost the 3 game series - losing the other 2 games by 1 point each. (Hawks over Lakers)
