Propose a trade

Trade Proposal

Upgrade your TE position while addressing WR depth.

Your team, which includes Kenneth Walker and D'Andre Swift, has a surplus of running backs but needs improvement at wide receiver and tight end. The opposing team, Team Four, is looking to bolster their WR corps, making this a mutually beneficial trade opportunity.

Fair Trade1-for-1Slight value win (Δ9)
Target: Team Four

Deebo Samuel

WRWR32· val 89

You get (1)

Dalton Kincaid

TETE8· val 80

By trading Deebo Samuel, you upgrade your tight end position with Dalton Kincaid, who has a higher aggregated rank. Team Four will enhance their wide receiver depth with Samuel, benefiting both teams.

Negotiation tip

Be clear about your needs and emphasize how this trade benefits both teams. Highlight the upgrade in tight end while addressing their need for a wide receiver.

Debrief

FantasyCalc sets the base rankings, with Boris Chen's tiers added in one-quarterback redraft leagues. We fit them to your league's settings, then adjust start advice for injuries, byes, news and recent form. Kalshi's player lines are one more signal: when they disagree enough with the experts, start advice shifts a little. Trade values stay separate.

Sleeper and Yahoo fantasy football. ESPN leagues aren't supported, so that one stays manually operated.

For 14 days, with no card. It's one trial per account, on Hobbyist. After that Hobbyist is $5 a month if you've added a card; if you haven't, the trial ends and nothing is charged. Pro is $15 a month with no trial.

No. It reads your league and recommends moves. You send the trade, make the add and set the lineup. It can't fat-finger your kicker for you.

Superflex on both platforms. Dynasty on Sleeper, where trade values account for years of experience. Yahoo has no reliable dynasty flag, so Yahoo leagues are treated as redraft.

In a Sleeper live draft, yes. Ask when you're up and it recommends a pick from who's left, with the board and your roster in view. It answers when asked; it won't tap you on the shoulder when you're on the clock. Yahoo live drafts aren't supported.

Not yet. Players only, including two-for-one packages, with a waiver pickup suggested for the open spot when a good one is available.

Two operators on Hobbyist, five on Pro. Each is tied to one league and keeps its own notes on your targets, the players you avoid, and your strategy.

Yes. Each plan has a usage allowance per billing period, larger on Pro, and an hourly cap of 40 messages (120 on Pro). Very long conversations can reach the hourly limit sooner. If the allowance runs out, chat pauses until it resets.

During the season. Before your draft there's nobody to start.
