Prospect Price Tag
An MLB trade evaluator that scores rumored deals the way front offices do — assigning a fair prospect cost to a rental starter or a rental bat so fans can argue from the same playbook.
analytics-leaning MLB fans, baseball writers, and Twitter trade takes who want a defensible number to attach to any rumored deal
- Pick a player and a team, get an automated 'market price' estimate in surplus WAR plus a 3-prospect package suggestion
- Side-by-side comparison of competing offers for the same player sourced from recent comparable trades
- Salary retention slider that updates the proposal and flags luxury-tax ripple effects
- Shareable one-image 'trade card' for social posts
The Astros trade-targets trend (500+ searches) is part of a broader fanbase that increasingly wants numbers behind their take, and the public availability of comparable-trade data makes a viable model possible now.
Active, sustained audience around MLB trade valuation — Baseball Trade Values runs a public trade board where users post trade proposals, and the broader fantasy-baseball trade-analyzer market is crowded (Dynatyze, Rosternomics, FantasySP, Razzball, Fantasy Alarm, Trade Analyzer, LineupExperts), confirming real baseline demand for trade-grading tools.Trade Boards - Baseball Trade Values ↗MLB Trade Calculator — Free Trade Values · Rosternomics ↗
Direct, well-established competitors already cover this exact niche: Baseball Trade Values is a full GM trade simulator with values for every major/minor player, and Rosternomics uses a Bayesian model that has graded every real MLB trade since 1985 — leaving little differentiated ground for a 'real-trade' evaluator.Baseball Trade Values: Accurate Player Trade Values ↗MLB Trade Calculator — Free Trade Values · Rosternomics ↗
Almost every comparable tool (Baseball Trade Values, Rosternomics, Razzball, Fantasy Alarm, the fantasy trade analyzers) is free or ad-supported/lead-gen for broader fantasy subscriptions — the proposed audience of analytics-Twitter fans and writers is notoriously resistant to paying for single-purpose trade-grade widgets.Baseball Trade Values: Accurate Player Trade Values ↗Fantasy Baseball Trade Analyzer by Razzball ↗
Sabermetric culture is durable and prospect-value discourse is a permanent fixture of baseball media, but real-trade evaluation spikes are seasonal (July deadline, winter meetings, free agency) and the model needs constant upkeep as prospect values re-rate — giving moderate long-term durability with cyclical peaks.
Public comparable-trade data going back decades and established prospect valuation frameworks (FanGraphs, Baseball America, crowdsourced boards) make the underlying model buildable; the main ongoing cost is maintaining current prospect values and trade comps.FanGraphs Baseball | Baseball Statistics and Analysis ↗Baseball Trade Values: Accurate Player Trade Values ↗
