I read that Flores wants to try and get both QB's close to a half each. He did not confirm it will happen but that was the thought. Not sure if that means 1st team plays 2nd half or not.
Maybe it ends up with Fitz playing into the 2nd quarter with Rosen relieving him to play with 1st team? just guessing.
