I'm definitely not sold on Nate Sudfeld as someone who can hold the fort for multiple games or even come off the bench and help the Lions win a game.
The benefits of Nate Sudfeld being brought back by the Lions are low cost option (assuming this is indeed the case), someone with familiarity /exposure with Lions coaches, players, and Offensive System, and apparent good working chemistry with Jared Goff.
The Lions need to address the QB in the draft. It should be a question of when in the draft, not if. A rookie QB with more upside than Sudfeld should be a goal for Brad Holmes and co.
