Then adjust your expectations? At this point that’s on you. Is the situation frustrating sure. But Isaac is the starter so just accept it.
Also in your post you detailed each game and how you are having no fun watching because Cam isn’t playing. Watching a game with your eyes and knowing Cam won’t be playing in it has nothing to do with not knowing what to expect at that point. You are mad because we are not an elite team without Cam and you expected us to have Cam.
We all get that, we are all frustrated, we all wish he wasn’t hurt but if you can’t enjoy football if Cam isn’t playing then that’s on you.
You saying that Barnes was more fun is simply crazy talk though. People forget so quickly.
