The Spurs have become careless with the ball
Over the past five games, the Spurs have committed the seventh most turnovers per game (16.4), and yet somehow this is actually a slight improvement compared to the team's first 13 games (17.1 turnovers per game). Unlike the previous two trends that have gotten progressively worse over the past five games, the Spurs' turnover woes have plagued them since the start of the regular season.
This turnover issue gets even worse, in fact, when factoring in the number of offensive possessions the Spurs have had. A staggering 17% of the team's possessions on that end of the floor have led to a turnover, which is good for second-worst in the league, per Cleaning the Glass. Teams have scored 74 points off of the turnovers the Spurs committed in the last five games alone, which is undoubtedly a massive contributor to the team's league-worst -10.8 point differential.
Part of this issue can be attributed to Jeremy Sochan's 18.1% turnover rate, which is easily the worst of the starting unit, but teaching a 19-year-old, 6'9" forward to be a secondary ballhandler in the NBA--in the starting lineup no less--is undoubtedly going to lead to some growing pains that will eventually begin to work themselves out. If you're asking me, I'm far more concerned with Keldon Johnson and Jakob Poeltl's 2.7 and 2.3 turnovers per game. Considering how much of the team's offense is running through both of them, this is something that absolutely needs to improve.
Beginning with tonight's game against the New Orleans Pelicans, we're going to be paying extra close attention to these concerning trends. Given the state of the team, the players' improvements over the course of the season (or the lack thereof) could determine how much longer they're in a Spurs jersey.
