Numbers preview: Western Conference finals – Golden State Warriors vs. San Antonio Spurs

Over the last four seasons, the Golden State Warriors (258-70) and San Antonio Spurs (245-83) have the league’s two best records and two of its three championships. But they haven’t faced each other in the playoffs in that time … until now.

When the Spurs won the title in 2014, the Warriors were knocked out by the Clippers in the first round. A year later, the Clippers beat the Spurs in the first round. Last year, the second-seeded Spurs were taken out in the conference semifinals by the Oklahoma City Thunder.

Now, we finally have the matchup we’ve been waiting for. The Warriors have reached the conference finals with ease, sweeping the Portland Trail Blazers and Utah Jazz. The Spurs have needed 12 games to get through the first two rounds and lost a starter (Tony Parker) along the way.

San Antonio is the only team that had a winning record against the Warriors this season, but it’s difficult to read much into those results given the circumstances (see below). Really, this is like a brand new matchup between what have been the two best teams in the league over the last seven months. It’s the league’s No. 1 offense (Golden State) vs. the league’s No. 1 defense (San Antonio).

After missing Game 6 in Houston with a sprained ankle on Thursday, Kawhi Leonard is expected to be back for Game 1 against the Warriors on Sunday (3:30 p.m. ET, ABC). The Warriors will have had five full days off since they last played.

Matchup notes:

The first meeting was the first game of the season for both teams. The second meeting was played without Curry, Thompson, Durant, Draymond Green and Iguodala for Golden State, and without Parker, Aldridge and Leonard for San Antonio. Durant also missed the third meeting, while Danny Green missed the first meeting.

Only the Raptors scored more points per 100 possessions against the Warriors than the Spurs did this season, and only the Celtics held the Warriors to fewer points per 100 possessions than the Spurs did this season. The point differential of 39 points was the Warriors’ worst in a season series in the last four seasons.

The Spurs grabbed 35.2 percent of available offensive rebounds, their highest mark against any opponent and the highest mark of any team against the Warriors. The Spurs’ 26 second chance points in the season opener were the most allowed by the Warriors all season. Aldridge’s eight offensive rebounds in that game were tied for the most in a game against the Warriors and his five blocks in the third meeting were tied for the most blocks in the game against the Warriors.

The Warriors averaged just 13.3 fast break points, their lowest mark against any opponent.

Leonard’s 15 free throws in the first meeting were the most he attempted in any game this season. He shot just 1-for-10 with Matt Barnes defending him this season, a mark which includes two games in which Barnes was playing for the Sacramento Kings. Leonard missed all eight of his 3-point attempts against the Warriors.

David West (plus-4) was the only Warriors player with a positive plus-minus over the three games.

Ian Clark’s 15 field goals in the second meeting were the most in a game against the Spurs this season.
