What happened: Julian Edelman said the Giants risk locker-room friction as J.J. McCarthy joins a quarterback room reset by injury. New York acquired McCarthy from Minnesota for a 2027 fifth-round pick after Jaxson Dart's season-ending knee surgery.
Why it matters: New York must stabilize the position with its starter sidelined for 2026. How quickly McCarthy earns trust in a new locker room will shape the continuity of the offense down the stretch.
By the numbers: Minnesota signed Max Brosmer to the 53-man roster as its emergency No. 3 quarterback following the move.
What to watch: Watch McCarthy's practice reps and who starts for the Giants in Week 5.
