Draft assistant + season helper for Yahoo leagues: live pick recs, optimal lineups, waivers, season sims, and league export.
The MFF Yahoo Helper adds a live sidebar to Yahoo Fantasy Football.
DRAFT MODE
• Live pick recommendations in the Yahoo draft room — best available blended with format-aware value-over-replacement, tiers, cliffs, roster needs, and ADP timing
• Reads your league's real scoring and roster slots automatically (PPR, superflex, flex types)
• Tracks every pick live and rebuilds instantly after a refresh
SEASON MODE
• Optimal weekly lineup from your league's exact slots and scoring
• Start/sit moves, Vegas matchup context, and waiver targets ranked by the points they'd add to YOUR lineup
• SIMS tab: 1,500 Monte Carlo season simulations — projected standings, playoff and title odds, week-by-week win probabilities
• One-click league export to your myfantasyfootball.co account
HOW IT WORKS
League settings and players come from Yahoo's own fantasy API for your logged-in league; the pick feed passively listens to the draft room's own connection (nothing extra is opened). Public NFL data from Sleeper's public API. Rankings are bundled and sync with myfantasyfootball.co. All processing is local.
REQUIREMENTS
A myfantasyfootball.co account with Premium is required — the helper unlocks automatically once you're signed in on the site. Rankings and recommendations are powered by that account.
