I HAVE NO CONNECTION TO FIVETHIRTYEIGHT. I didn't ask them for permission to make this. If they ask me to take it down, I am happy to do so. I'm a huge fan of the work they do. Nate, please don't sue me.
FiveThirtyEight made a system for comparing your own NFL forecasts to those made by their Elo rating system. When multiple games are being played concurrently, it's a bit of a hassle to track how the teams are doing relative to what your forecasts were.. so this Chrome extension was born. It pulls current game data from the NFL, and when you're on FiveThirtyEight's Elo game results page, it uses some hacky javascript to insert the current quarter, time remaining, and score for each game that is currently live. When there is a live game, the page will refresh every minute. When there is no live game (and the page is still open for whatever reason), the page will refresh every hour. If the page isn't open in your browser, the extension will just sit idle.
The code is messy and shameful and doesn't have much in the way of error handling, but the risk of trying it out is slim to none (if it doesn't work, just remove the extension). The source code is here: https://github.com/kairozu/Elo-Live-Score

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
