So one thing that will likely be overlooked, but if they end up 4th in the division by end of season. They'll likely have one of the easiest schedules in the league next season. A big reason why the cliche of worst to first happens so frequently in the league is the forced parity of the scheduling based on past season division records.
If they use their cap space wisely, somehow figure out their QB and oline situation, they could manage something next year.
Probably best in the long run to suck bad next year too though, but would be hard to do with said schedule and this defense. Unless they do something like trade away talent for picks and go full rebuild, but I don't know when the last time they did that was so wouldn't plan on it.
