# Showing ESPN Receiver Tracking Metrics using weighted radar charts _The whole idea for these charts, and the text and stats, are from [Seth Walder](https://twitter.com/SethWalder) of ESPN Sports Analytics; Toph just helped with coding._ These radar charts depict the three components of [ESPN’s Receiver Tracking Metrics](https://projects.fivethirtyeight.com/nfl-receiver-rankings/) (RTMs): Open Score, Catch Score and YAC Score. Because Open Score is the most important of the three components — it is the most stable, correlates strongest with a receiver’s yards per route run and is the most predictive of future production — its axis is twice as long as the other two components’.

Below you can select multiple players within the same season to compare their RTMs components or look at how a single player’s RTMs have changed over time. ESPN’s Receiver Tracking Metrics use NFL Next Gen Stats player-tracking data and an explainer for how they work [can be found here](https://www.espn.com/nfl/story/_/id/34649390/espn-receiver-tracking-metrics-how-new-nfl-stats-work-open-catch-yac-scores).
