Credit 3s for record margin of victory

DALLAS -- The Mavericks' 122-86 victory that sent the Los Angeles Lakers into an early offseason and Phil Jackson into retirement goes down as the largest margin of victory in Game 4 of a series sweep in NBA history.

Chalk it up to the Mavs' amazing 3-point shooting. They made 20-of-32 to tie the 1996 Seattle SuperSonics for most 3s in a playoff game. Jason Terry made 9-of-10 to tie the NBA record for most 3s made in a playoff game.

According to ESPN Stats and Information, for the series, the Mavs made 49 3-point field goals, an NBA record for a four-game playoff series. L.A. made just 15 3-point field goals and went just 4-for-31 from 3-point range in the fourth quarter during the series.

More mind-blowing numbers from the crack research department: Dallas did most of its damage off of catch-and-shoot jumpers according to game-tracking. The Mavericks hit 18-of-30 jump shots without taking a dribble in Game 4.

The alarming part for the Lakers is more than one-third of those shots came from Mavericks shooters who were unguarded. The Mavericks made 8-of-11 field goal attempts, all coming from three-point range, when left unguarded by Lakers defenders.
