If you have a kicker with a starting job, don’t worry about kicker. 1-32, they are basically the same.
DST can be a different story. I would say there is really three types of DST. The first type you plug into your lineup and leave there except on a bye week. I would say the top ten fit here. The next ten are useful, but will make you nervous. As I abhor the idea of filling a bench spot with a defense, this usually means they will have to be in the lineup, but are scary. Some weeks you might drop an extra TE for a defense if your main one is playing an elite offense. The final 12 defenses are bad no matter who they play. These are defensive units I wouldn’t want, regardless of the matchup.
These are my personal groups. If you disagree, feel free to move some teams around.
Steelers, Jets, Ravens, Packers, Vikings, Eagles, Bengals, Patriots, 49ers, Dolphins
Saints, Titans, Chargers, Giants, Redskins, Cowboys, Chiefs, Texans, Falcons, Bears
Group 3 is everyone else.
