Points Per Possession is going to be skewed in the Spurs because the Spurs don't foul. That's part of the Spurs' defensive scheme and has been since Pop became coach. Think about it, even if you let teams shoot 55% from the floor but don't foul anyone ... that's better Points Per Possession than a team that holds team to 40% but fouls. That's because the NBA shoots 74% from the free throw line. Of course if you don't foul, you aren't going to give up 57% field goal percentage (~57% = equivalent FG% for each possession you send someone to the line) even if you are the Phoenix Suns.
Talking about the Phoenix Suns, they are 14th in the league in Points Per Possession. So unless you think the Suns are a better than average defensive team, you can pretty much throw that stat back in the trash.
Don't foul at all and give up 55% field goal percentage and you'd lead the league.
