If the Patriots don't trust Jayden Daniels to not try to get truck sticked every time he runs the ball or think this season being a big outlier for him is a concern, McCarthy would make some sense. He'll end up going top 12 anyway with the Falcons, maybe Vikings and Broncos all needing QBs. Even if the Vikings bring back Cousins, that's still where I think he will end up.
This QB class in general just seems really over hyped.
