What happened: Harbaugh's first weeks with the Giants have been defined by tougher standards and aggressive quarterback-room churn, including a 2027 fifth-round trade for J.J. McCarthy. Jameis Winston still opens as the starter after his pre-season extension, even as attention turns to how quickly McCarthy could force the issue.

Why it matters: That matters because the quarterback decision will shape whether Harbaugh's tone change becomes a fast turnaround or another long wait at the position. The pressure reaches the defense too, with Abdul Carter, Kayvon Thibodeaux and Arvell Reese needing to generate more disruption for a team coming off a 12-point outing.

What to watch: The next read is whether Winston can hold off the first real push for McCarthy snaps. The other one is how quickly Carter, Thibodeaux and Reese turn promise into pressure.
