Drew Lock occupies your superflex slot in this snapshot. Darnold is already on the bench, so follow his recovery before considering him for a future lineup.
If Price remains limited, compare healthy options for the next eligible lineup period. Check expected playing time, then confirm Sleeper's lock and AutoSub rules before any change.

Price is questionable in your flex slot, and RJ Harvey is out on your bench. Start by checking their recovery and the expected roles of your other flex options before paying for more depth.
Darnold is also out on the bench, with Drew Lock in your superflex slot. Compare the actual available players and waiver timing before choosing a bid. A pickup cannot replace a locked player.

Before you start
What you need for Sleeper
The correct sport and season
NFL and NBA leagues are supported. Check the season and selected team if discovery does not show the league you expect.
Realistic data expectations
For an explicit regular-season NFL week, League Loom can calculate projections from Sleeper projected stats and your league scoring. Partial coverage is labeled; missing projections are not zero. Ownership percentages are unavailable.
Worked example
Turn a roster check into a waiver question
Illustrative walkthrough for a sample Sleeper football league. No real player availability or bid outcome is implied.
Identify your team
Confirm the league, season, and selected roster so an available-player search uses the correct league.
Check your resources
Ask for available players, roster needs, and remaining FAAB or waiver priority. Have the assistant flag any missing field.
Review the trade-off
Ask which available player fits an immediate need and what you lose by dropping someone. A suggested bid is the AI's judgment, not a prediction of competing bids.
More about this connection
Sleeper league data can be read with a username, so setup needs no Sleeper password or account token. League Loom supplies your league context; your AI tool interprets it.
For example, the assistant can compare available players with your roster needs and use your remaining FAAB and waiver priority where returned. For an explicit regular-season NFL week, League Loom can calculate Sleeper league projections from available projected stats and your scoring settings.
Partial or unavailable coverage is labeled. Ask the assistant to identify missing information and cite any outside research separately. All current tools retrieve or analyze data; you make roster moves in Sleeper.
Before you connect
Questions, answered
Is the Sleeper connector free?
League Loom is free, with no subscription or per-league fee. Fair-use request budgets apply. Your chosen AI service has its own account and access requirements. All current tools retrieve or analyze data; you make roster moves yourself.
Do I need a Sleeper password?
No, just your Sleeper username. Sleeper's data is public, so that's all League Loom needs to find your leagues and read your team.
What can I ask about my Sleeper team?
Anything League Loom can read: byes and injuries, the best available waiver adds, your weekly matchup and score, standings, your roster, and your draft, for one league or all of your teams at once.
Does my Sleeper username grant write access?
No. A Sleeper username only finds public league data.
Can League Loom see my FAAB budget and waiver priority in Sleeper?
Yes. For Sleeper leagues specifically, League Loom reads each team's remaining FAAB budget and waiver-claim priority, so you can ask how much you have to bid before making a move, or where you rank in the waiver order.
Does League Loom show my Sleeper taxi squad and IR?
Yes. It reads taxi-squad and IR assignments straight from your Sleeper reserve slots, so you can ask who's stashed, who's eligible to be activated, and how those roster spots affect your active lineup.
Can League Loom help with dynasty or keeper decisions in Sleeper?
It can read roster construction, player data, and recent transactions. Supply any keeper costs or contract rules that are not returned, and ask the assistant to separate those assumptions from league facts.
Is League Loom free?
Yes. The MCP server and connector are free, with no subscription and no per-league fee. Fair-use request budgets apply. Connect supported ESPN, Sleeper, and Fantrax leagues and ask questions from your AI tool.
Can I set League Loom up on my phone?
Setting up is easier on a computer, because that is where the connector settings in Claude and ChatGPT are designed to be used. You can still start from a phone browser by opening those settings from our home page, and if you would rather finish later, use Send to my computer to email or message yourself the link. Once the connector is added, asking questions works fine from your phone.
