6. 2017 Cleveland Browns
NFL history buffs might be shocked to find the winless 2017 Browns so early on this list, as there are still three one-win teams waiting to be put out of their misery. But Cleveland wasn’t as bad as their record suggests, ranking 14th in the league in yards against. Their biggest weakness: turnovers. The Browns gave the ball up 41 times and had just 13 takeaways of their own.
