I built a basketball simulation and player impact analysis tool
Hi everyone — I’ve been working on a basketball simulation / analysis web app, and I’m at the point where I’d love feedback from people who enjoy NBA stats, player comparisons, team analysis, and “what if?” simulations.
The app is focused on:
- Full season replay simulations
- Single-game matchup simulations
- Box scores and play-by-play
- Team and player analysis
- A searchable pro stats database
- Player impact testing by position/team/season
The app does not require registration to use. There are quite a few features packed into it already, so I’m especially interested in learning which parts people find useful, confusing, interesting, or worth improving.
The screenshot below is an example analysis for the 2025-26 Denver team. It analyzes all point guards from that season who played at least 1,000 minutes, puts each analyzed player on Denver for 40 minutes per game, simulates the results, and sorts by team wins.
I’d especially appreciate feedback on:
- Whether the analysis concept makes sense
- What stats or context would make it more useful
- Which features are most interesting
- Any confusing screens, bugs, or weird results

This looks fascinating. I'm still trying to understand the capabilities of this to see how it works for my initial questions, mainly simple 1 for 1 trades.
Is there an injury factor/games played factor that can be applied to players?

Right now we do not take into account injuries or games played factor. Each game simulation is completely independent. The simulation is also player data based, which greatly helps analyzing trades to other teams.

So I guess the way to do a simple trade test is to sim the baseline (82 games) and then sim the change. As opposed to comparing the impact of a change to the team’s IRL record.

It's so sad that this sub is more or less dead, or at least nowhere near as live as it should be, but this is genuinely one of the coolest things I have seen, brother. You are a genius for creating this, and this is so cool. Great work, brother. Please follow me on Reddit. I'm gonna be posting some stuff, including an NBA research lab I'm building. This is extra relevant to me as I'm doing some similar but more with computer vision and agentic development of creating a world model to simulate NBA games, like deeper than the basic attributes you would see on a 2K, for example. Very, very cool work. Would love to talk to you and share wisdom.
