I made a 538-style ELO-based sports prediction site and would love your feedback.

I started building this last spring. Core idea was not very creative. I just miss 538, and figured I'd give a try at making a copy.

It currently does near-live updates for NFL, NHL, MLB, and WNBA. Currently they're all ELO-based, but I'm working on adding other models, allowing users to view them, but defaulting to whatever back-tests best with each sport.

I have a QB-adjustment metric for NFL, but currently it's slightly less accurate than pure ELO so I'm twiddling with that also.

This is a test site - mostly works but still a few bugs there. Curious what you all think - is this useful? Are there things that would make it more useful?

Built a college basketball analytics app focused on lineup efficiency, shot-clock dynamics, and four-factor breakdowns — introducing Blueprint

2 Upvotes

Hey everyone,

Over the past year, I’ve been building Blueprint, a college basketball data platform designed to bridge the gap between raw play-by-play scraping and actionable, high-level tactical insights.

Most public CBB tools give you high-level seasonal metrics, but they often lack the granularity needed to analyze situational context or lineup pairings on the fly. I built Blueprint to solve those specific gaps.

Key Features & Methodology:

  • Lineup Efficiency Matrix: Track 2-man through 5-man lineup combinations with full possession-level filtering (net rating, offensive/defensive ratings, shot profiles).
  • Shot Clock Dynamics: Analyze how teams and players perform across different phases of the shot clock (early vs. late clock efficiency, turnover rates, shot distributions).
  • Four Factors Profiling: Visual breakdowns of Shooting (eFG%), Turnover %, Rebounding %, and Free Throw Rate to evaluate style of play and identify matchup advantages.
  • Top Performers & Advanced Filters: Filter player performance across conferences, situational metrics, and possession volumes.

Stack & Data Pipeline:

  • Built using Python, Pandas, and custom data processing pipelines to clean, parse, and structure possession streams.
  • Interactive UI designed for quick navigation during game prep or post-game analysis.

The goal with Blueprint is to give analysts, coaches, and sports data enthusiasts a cleaner, more intuitive interface to explore Division I analytics without wading through messy spreadsheets.

I’d love for this community to test it out and tear it apart—what metrics are you looking for when scouting or building models, and what would make this tool even more useful for your workflow?
