You read it, hear it, see it every season: Don't draft a kicker until you absolutely have to. Numbers don't lie. There's just no need to do it. Yet, people still do it. This draft season already, I've seen it happen with eight rounds to go, seven rounds to go, you name it.
Three rounds to go should be the absolute minimum and that is only if it is a deep roster and you've already filled out all the bench spots you can.
