Is it lost on you that divisional teams play each other twice every year?
The topic of the thread is basically whether the Bills will win the division. You cited the Bills difficult schedule as a reason they might not. That is an almost entirely invalid reason.
Now if you're saying "team x" within our division has improved, thus our schedule is harder than 2019, there might be a small point but the fact remains that each team plays the others twice. Are you saying the Patriots have improved? If so, make that the basis for your argument.
