The biggest personnel storyline this season will be about Jeremy Sochan and what the Spurs plan to do with him. He's found himself coming off the bench after starting for the first two-plus years in the league. That's telling. Bench players just don't have the same security as starters do, and I'd argue that after Luke Doncic was traded, nobody is safe (except for Victor Wembanyama).
However, there's a special kind of uneasiness for players when they see their roles morph from consistent contributor to bench and energy guy. It's not too late for the Polish forward, though.
