Something in the back of my mind is if Gailey's offense in actuality is less complicated than O'Shea's, what if Rosen starts to click because he has to process less and beats Fitzpatrick out for the starting job? The emergence of Rosen would be a great issue to have this year.I've been on board with no putting Tua on the field all year. I don't think the need is there and count me in the group who would like to see Rosen first if things aren't going well with RF.
Overall though, I don't think there needs to be a concrete plan in place. Play it by ear is the right approach here. There is no need to set anything in stone.
