Story summary

J.J. McCarthy secured the starting quarterback position for the New York Giants after his impressive performance against the Saints in Week 6, where he threw for 243 yards in just over an 11-minute span, setting an NFL record. Despite losing to the Saints, McCarthy's fourth-quarter effort earned him a higher fantasy football ranking of QB5 and increased his roster percentage to 11.4% in ESPN leagues. The Giants' head coach John Harbaugh announced that McCarthy would start against the Houston Texans in Week 7. McCarthy’s mobility presents more offensive options compared to previous quarterback Jameis Winston, as he can gain rushing yards while also providing passing threats. With the running back depth chart unsettled and Najee Harris recently released from the team, McCarthy’s role could be crucial for the Giants' offense moving forward.
