It could be a good move the problem is that removing divisions causes a massive runoff effect on the rest of the standings for the playoffs. Hell, the way they are now is confusing once you get passed the division and head-to-head. Imagine having to rewrite the rules for the standings with a new format. There are threads about who the bills will play based on different scenarios and some of them have the same W/L for different teams and but the standings are different.
All things considered though, I don't care if a losing team makes the playoffs. If you're the best in the division then that's what you are even if you are a 6-10, 7-9 team.
