Mac Jones arrives in San Francisco with swagger that fits Shanahan’s offense, and the 49ers want to take over the Saints’ home field in Week 2. His locker-room energy and humor have teammates buying in as the offense seeks a steady, multi-faceted attack.

Demario Davis and New Orleans aim to slow Christian McCaffrey and pressure Jones, while San Francisco expects McCaffrey to anchor a heavy-volume game plan. Fantasy angles lean toward McCaffrey’s volume and Pearsall’s growing role, with a predicted low-scoring clash that tests both defenses and play-calling limits.
