The two most useful documents in fantasy football are published every week and most people read neither properly: the depth chart and the injury report. Between them they answer the question that decides most start-or-sit calls, which is not "is this player good" but "is this player going to be on the field".

A depth chart is a claim, not a fact

A depth chart says who a team lists first at a position. It does not say who plays the most snaps, and the gap between those two things is where the value is.

What to actually take from it:

  • Movement matters more than position. A receiver who was third and is now second told you something. A receiver who has been second all year told you nothing new.
  • Running back ones and twos are nearly meaningless in isolation. Many teams list a starter who plays half the snaps. The change to watch is a third-stringer moving to second, which usually means the team has decided something.
  • Offensive line changes travel. A new left tackle is a fact about the quarterback and the running back, not about the tackle.

Our depth charts show up to three deep at every position with an arrow where someone moved since last week, which is the part worth two seconds of your attention.

Reading the injury report properly

The designations mean specific things, and the practice column means more than the designation:

  • Out is settled. There is no news coming.
  • Doubtful is close to settled. Historically very few doubtful players play, and those who do rarely play a full workload.
  • Questionable is the one that matters, and on its own it tells you very little — it covers everything from a genuine coin flip to a veteran being managed.

The way to break a questionable tie is the practice participation, three days of it:

  • Did not practise, did not practise, limited — that is a player who is probably not right even if he dresses.
  • Limited, limited, full — that is a player who is playing.
  • Full all three days with a questionable tag is usually a team keeping an opponent guessing.

Putting the two together

The genuinely actionable situation is not a star being out. Everyone sees that, and the price adjusts. It is the second-order effect:

  1. A starter is ruled out.
  2. The depth chart tells you who moves up — and whether the man behind him also moved, which tells you how the team sees the replacement.
  3. The replacement's snap share the last time this happened tells you whether he takes the whole job or splits it.

Most weeks that chain produces one or two names worth a roster spot before anyone else notices, which is the entire edge available to somebody who is not watching every snap of every game.

Where the numbers come from

Ours come from two places and we say which on every page. Rosters, teams and stats come from the News Hub Fantasy data pipeline. Injury detail and depth charts for the NFL come from nflverse, published under CC-BY 4.0, which is why the credit line is on the page.

Practice participation is the field to look for, and it is the one that is missing from most free sources. It is on our injury report, filterable by team and position.

The one-minute version

  • Check who moved on the depth chart, not who is on top of it.
  • Treat "questionable" as unresolved and read the practice column.
  • When a starter is out, look one row down and ask whether the job splits.
  • Do it on Saturday, not Sunday at noon.

Follow the players you care about and we will flag their injury news in your feed and your Sunday briefing, so this becomes something you read rather than something you remember to check.
