Problem

Fantasy drafters lean on pre-season Average Draft Positions with little visibility into how those picks actually panned out — which players were consistently over- or under-valued.

Build

Built an analysis platform over eleven seasons of NFL data (2015–2025): compare ADPs against end-of-season fantasy rankings across 2,700+ players, with a Draft Helper, position-specific value/bust analysis, live 2026 ADP rankings, and a Survivor League pick tool with win-probability analysis.

Outcome

A data tool (5,000+ data points) that helps drafters spot overvalued and undervalued players across eleven seasons and make smarter picks.
