If you've made the right start/sit decisions through the first four weeks of the fantasy football season, then you're probably in a good spot in your league. But if you've made the wrong decisions, you might have some ground to make up and some work to do.
Not every player is a Patrick Mahomes or Lamar Jackson or Alvin Kamara who can be kept in a fantasy lineup all season no matter the matchup. Some players are borderline calls who might need to be benched when they're going up against a strong defense and then reinserted later when a better matchup arises.
