From the video

JJ McCarthy, the quarterback that made Justin Jefferson, look like Marvin Harrison Jr. last season, is now going to team up with Malik Neighbors for the New York Giants. But with how bad Jamus looks, I wouldn't be surprised if once McCarthy knows the playbook in two to three weeks, JJ McCarthy is under center for the New York Giants.
STACKED’s take
Negative signalRole
Giants backup QB; likely starter in 2–3 weeks; threatens Nabers upside.
Acquired by Giants as backup QB; expected to take over as starter within 2–3 weeks once he learns the playbook, given Daniel Jones's poor performance. McCarthy is noted as the quarterback who made Justin Jefferson look elite last season, but his arrival creates uncertainty for Giants receivers. This QB transition negatively impacts Malik Nabers' fantasy outlook.
