Ugh this decision is gross! my first QB is lamar jackson so I’m set there.
My QB model has Fitz projected to be the QB11 this week and Brady the QB20. ROS Fitz is projected to be the QB12 and Brady the QB17. So in either case I would go with Fitz and just monitor the situation to see if there are any rumblings about them switching back to Rosen as the season comes to a close. My full QB model is below for reference. Hope that helps. Good luck!
