HooperROI Changelog

Overview

HooperROI is a project designed to assess the value (or return on investment) of NBA player contracts by analyzing player salary data and performance metrics. The key metric, known as the Overpay Index, contextualizes a player's salary by comparing it to the league-wide cost per win share and their team's expenditure per win share for said player. This metric determines whether a player is overpaid or underpaid, and the final result is presented as a Contract Value Rating (CVR) on a 5⭐ scale.

The application is built using Python with libraries such as Pandas, NumPy, and Flask. The data is processed to compute a variety of useful metrics including the Overpay Index & Contract Value Rating. Users can input a given season and a player's name via a simple web interface and retrieve an analysis of their contract value.
