That was my point. He doesn’t have to be. If he is healing well and it doesn’t look like any long term ramifications they don’t need him to start. They have Rosen. Maybe it’s not a risk they will be willing to take we will have to see.
You fail to acknowledge all the things that might have played into everything. If JB is the starter next year and we still haven’t improved the passing game you will have a point. This year has been a getting to know you season for everyone. From coaches to the players on offense. From injuries to the coaches and QB getting a feel for each other. To keeping things simple so it doesn’t overwhelm a QB who was just handed the keys. Think of all the pressure that had to be on him after Luck retired.
