The team manager · the season pass
It manages your team with you, every week.
This is your team's dashboard: the lineup check, the market watching your players, your roster with the week's story on every player, and the waiver shortlist. Website on your work screen, app on your phone, same brain.
- Lineup check. Your lineup vs Bird Dog's, every swap graded STRONG, LEAN, or TOO CLOSE, with the reasons named.
- Projections that move all week. Every player re-projected daily from live Vegas props, in your league's exact scoring.
- Alerts before kickoff. Starter ruled out, market repricing one of your guys, your phone gets it while there's still time to act.
- Tuesday waivers. Only players actually available in your league, ranked by how much they upgrade YOUR lineup. If nobody does, it says so.
- Ask Bird Dog. An AI chat that knows your roster and this week's numbers. “Start Rice or Nabers?” Answered, with receipts.
The draft guide · free
It sits next to you on draft night.
The live big board: every player ranked by value for your league's exact scoring, drafted players falling off as picks happen, your roster building itself on the right.
- A value-based big board built for your league's exact scoring. It ranks players by how hard they are to replace, not just points, and re-ranks with every pick.
- A Chrome extension that puts the board inside your ESPN draft room. Drafted players fall off on their own, steals get flagged.
- A printable cheat sheet for the paper-draft purists, same value math, one page.
The difference
ESPN projects your players once.
Bird Dog re-projects them every day.
Platforms like ESPN set a player's projection early in the week, and it barely moves, no matter what happens.
Ours updates all week, because it's built on live player props, repriced the second the money moves. When a line jumps on your guy, your phone gets it.
Measured: market numbers were more accurate than platform projections across the full 2025 season.
Sunday 9:04 AM - the market just moved on your guy. Your platform still shows the same projection it showed Tuesday.
How it works
It plugs into the league you already play in.
Bird Dog isn't a new league and it doesn't replace ESPN. It connects to your existing league, watches it all week, and tells you what to do.
Connect your league
ESPN or Sleeper, about 30 seconds, no passwords. Bird Dog pulls your real roster, your league's exact scoring, and your matchups.
It watches everything, all week
Live betting lines, injuries, usage, matchups. Every player on your roster and every free agent in your league, checked daily.
It all lands in your dashboard
Everything feeds into one dashboard for your team: a lineup check with the swaps to make, your waiver shortlist, and Ask Bird Dog. Push alerts when something can't wait. You make the moves on ESPN; Bird Dog never touches your team.
Your league doesn't change. Your decisions do.
Be the guy the group chat hates losing to.
Your season with Bird Dog
Draft night to the playoffs,
here's what Bird Dog does all season.
Draft night: rob them politely
The whole room is drafting off ESPN's default rankings, one generic list built for an average league that isn't yours. Your board runs your league's exact scoring, knows a steal from a reach, and re-ranks live as picks come off. Same room, different weapon.
See the live board →11:42 AM: the text that saves your week
Your WR2 got scratched while you were buying beer. You already got the push, with who to start instead and why. The guy who didn't? He finds out after kickoff, lineup locked, zero on the board.
See the lineup check →9:00 AM: raid the wire first
Every Tuesday, Bird Dog scans every free agent in your league and flags the ones who'd actually upgrade YOUR lineup, proof attached. No hunting, no side-by-side comparing. You just look at the shortlist and decide who to claim.
See waiver targets →All week: we watch the money
Player props move when something's up, a quiet hamstring, a role change, a shootout brewing. The market knows before the beat writers type it up. When it moves on your guy, so does your phone.
Any time: Ask Bird Dog
Bird Dog has a built-in AI chat that knows your roster, your matchups, and this week's numbers. “Start Rice or Nabers?” “Who's my worst starter?” “Is my RB2 droppable?” Straight answers, receipts attached.

Why Bird Dog
Same league. Two kinds of GM.
ESPN's draft list is one static ranking for every league in America, barely adjusted to your scoring and blind to value.
A live value board: it ranks every player by how many points he gets you over the next-best guy at his position, in your league's exact scoring, re-ranked every pick.
Trusts a projection ESPN wrote on Tuesday that hasn't moved since.
Bird Dog re-runs the call all week on live betting lines, so Sunday's decision uses Sunday's information.
Spends the evening scrolling the wire, sorting stats, comparing guys by hand.
If anyone available makes your team better, he's on your shortlist with the proof. If nobody does, it says that too.
Finds out his RB was inactive when the group chat starts laughing.
Got the push at 11:42, swapped him, moved on.
Every call shows its receipts
Matchup rank, usage trend, market line, injury status, named, on every recommendation. If we can't show the why, we don't make the call. You'll never defend a start in the group chat with “an app told me.”
Honest when it's a coin flip
Some calls are genuinely 51/49, and we label them TOO CLOSE instead of inventing confidence. That's why you can trust the ones marked STRONG. Sharper numbers than platform defaults, measured across a full season, not vibes.
Your leaguemates are winging it. You don’t have to.
