Nobody will trade for Dak. He’s an average QB who had his “MVP runner up” year against the worst pass defenses in the league, and he’s been part of teams that have been beating up on even more horribly managed and less talented teams in the division for years and playing on teams with some of the best TO differentials on defense.
In other words, this team will only go as far as Dak will take them as Jerry Jones said (one of the truthful things he said), and he’s not going to take them or any other team anywhere. He’s a choker in the playoffs and against good teams because he’s mentally weak and doesn’t have the arm talent to compete with them.
