How do you know things won't get better?
As far as your question of "What have you seen that indicates this?" For one thing, they got the Bills to the playoffs last year. I know, you will probably say they backed in. The fact is the won enough games to qualify for the playoffs. Management is getting us out of a financial mess. This season needed to happen. We are all guessing what will happen. Until I am proven wrong, I like to believe that things will improve. You like to things will stay the same or get worse.
I prefer my outlook. If focusing on all the bad things that can happen in the future brings you comfort, then best of luck to you.
