When considering which kicker and/or DST to draft, the thing to remember revolves more around "when," not "who." Because kickers and defense/special teams are the easiest parts of a starting lineup to replace, it's important to be flexible with who you roster at those positions and not to get too attached unless you truly have a difference-maker, which is often tough to determine before the season starts.
When thinking about who to target at both kicker and DST, start first with the elite options at each position, then consider early-season schedule above all else. Building rankings with that second criterion in mind will make these tiers look less like other positions because we're generally not looking to project how the final point totals will look at the end of the season for most of
