Can afford to lose - Jeremy Sochan
Perhaps the player on San Antonio's roster with the most variance in how he is viewed, Jeremy Sochan has been an extremely solid player in his 1.5 seasons with the Spurs. He has demonstrated his above average passing, court vision and defense, and has shown why he can absolutely have a role on this team for years to come.
But while his unique skillset is highly intriguing in the long term as well as useful in the here and now, it would be a stretch to say that the Spurs could not afford to lose Sochan going forward. Simply put, offensive gravity matters in the NBA, and Jeremy has not demonstrated enough proficiency on that end of the floor to earn himself the label of untouchable.
As previously stated, the only player on San Antonio's roster that can truly be set aside as a franchise cornerstone is Victor Wembanyama. That is just by nature of the fact that we can truly say he has All-NBA (and even best in the world) potential.
Sochan's role as a passer, defender, and general offensive connector is a valuable one. His contributions to this team are palpable, and the Spurs should do their best to keep him around. But if push comes to shove, San Antonio could find success without him, too.
