What happened: San Antonio spent Saturday pointing fans toward its Open Scrimmage on Oct. 4. The public session arrives during the Spurs' opening week of training camp as preseason preparations move into view.

Why it matters: The workout turns San Antonio's Oct. 4 open-scrimmage plan into the first public checkpoint of camp. It also gives fans an early look at the group before preseason games begin.

What to watch: Watch for which camp players take the floor Sunday and whether San Antonio uses the event to hint at early preseason groups.
