Marlowe Wax headlines the Chargers’ depth test as SF’s Nick grade of the backups surfaces in a 30-23 setback. Wax’s trio of standout plays, plus DJ Uiagalelei’s mixed bag and Mordecai’s roller coaster, shape roster debates with 53-man cut looming. Luke Grimm’s punt-return hiccups steal attention from a late TD, while Guerendo’s speed and Gadsden II’s steadiness add intrigue for Week 1 depth charts.
