Giants' Matt Nagy ready to open up playbook for J.J. McCarthy's first start

Key Points:

• The Giants' offensive coordinator Matt Nagy has had to adjust the playbook significantly due to quarterback changes, losing about 30% of plays involving dual-threat quarterbacks after Jaxson Dart's injury and Jameis Winston's subsequent starts.
• Rookie J.J. McCarthy, who recently became the starter, has restored some of the lost playbook flexibility, showing strong command of the offense and delivering a historic fourth quarter performance with 243 passing yards and three scoring drives against the Saints.
• McCarthy's ability to operate the no-huddle offense and manage the game has impressed the coaching staff, who now feel confident entrusting him with the full playbook after gradual increases in his responsibilities.
• Teammates like Isaiah Likely and Malik Nabers emphasize supporting McCarthy by creating opportunities and maintaining trust, highlighting the importance of chemistry amid frequent quarterback changes.
• Despite the challenges of starting on the road as underdogs, the Giants' staff believes McCarthy is ready for the role, crediting quarterbacks coach Brian Callahan for his preparation and development.
