FantasyBlockbuster

A fantasy-baseball trade analyzer that watches the MLB trade wire in real time and tells you exactly how a reported deal moves your specific roster — projected wins gained/lost, keeper value shifts, and a one-click counter-proposal to send to your league.

Target user

competitive fantasy baseball players in dynasty and redraft leagues

Features
  • Auto-import of your league roster and scoring settings from Yahoo, ESPN, Fantrax
  • Instant impact calc for every reported MLB trade on every roster in your leagues
  • Dynasty prospect value tracker that updates when a minor leaguer is moved in a deal
  • 'Counter-offer generator' that proposes fair-value swaps using your bench and prospect pool
Why now

Every rumored MLB deadline deal directly reshapes fantasy values, and the Blue Jays sell-off speculation means lots of name movement is coming in the next 7 days.

Demand
6/10

Fantasy baseball is a sizable, growing market (~$705M in 2024 per WiseGuyReports) and multiple dedicated trade analyzers already compete for users (FantasyPros, FantasySP, RotoBaller), confirming real demand, but the broader trade-analyzer need is already well-served.Fantasy Baseball Market Size, Growth & Trends to 2035Fantasy Baseball Trade Analyzer | FantasyPros

Whitespace
5/10

Crowded field of direct competitors (FantasyPros My Playbook, FantasySP, RotoBaller, TheTradeAnalyzer, HarryKnowsBall, Dynatyze, DynastyDugout); the 'real-time MLB wire → roster impact' angle is differentiated but FantasyPros already ships Trade Finder + Lineup Assistant on top of an analyzer, leaving narrow whitespace.Fantasy Baseball Trade Analyzer - Who To Trade - RotoBallerMLB Trade Analyzer | The Trade AnalyzerHarryKnowsBall: Dynasty Baseball Rankings and Trade Calculator

Monetization
7/10

Willingness to pay is clearly demonstrated — FantasyPros explicitly walls the MLB Trade Analyzer behind its My Playbook premium package alongside other league-syncing tools, validating a subscription model targeting competitive players.Fantasy Baseball Trade Analyzer | FantasyProsDynasty Baseball Trade Calculator - harryknowsball.com

Longevity
7/10

Fantasy baseball is a decades-old recurring seasonal product; MLB trade deadline drama (e.g., Blue Jays sell-off speculation) recurs every July, guaranteeing annual demand spikes, though usage outside the season window is thin.Fantasy Baseball Market Size, Growth & Trends to 2035Industry Research - Fantasy Sports & Gaming Association

Feasibility
6/10

Buildable but non-trivial — requires real-time MLB transaction ingest, projectable league-sync (ESPN/Yahoo/CBS APIs that FantasyPros already exploits), and projection models on top of a roster-impact engine; the 7-day deadline window is tight for a first release.Fantasy Baseball Trade Analyzer | FantasyPros
