What happened: J.J. McCarthy stepped into the starting lineup for the New York Giants on Sunday and delivered a victory in his debut atop the depth chart. On the same slate, Kyler Murray and the Minnesota Vikings secured a 16-10 final win to keep their undefeated record intact.

Why it matters: The dual outcomes give both front offices early validation after the Vikings sent McCarthy to the Giants to reshape their quarterback rooms. Minnesota continues to pace the conference contenders with Murray under center, while New York gains immediate stability at the position.

What to watch: McCarthy looks to build on his winning debut as New York's starter next week, while Murray and Minnesota aim to extend their unbeaten run.
