## Description

Tradyr puts dynasty fantasy football values everywhere you already research players — no more flipping between tabs.

A small, colour-coded badge appears next to player names showing the Tradyr Composite: a blended score from KeepTradeCut and FantasyCalc that gives you one number to trust at a glance. Click any badge to open the full player profile on tradyr.app — historical value chart, rest-of-season projection, advanced stats and metrics.

WHERE IT WORKS

 • KeepTradeCut — rankings, player pages, trade calculator
 • FantasyCalc — rankings and trade tool
 • FantasyPros, Yahoo Fantasy, ESPN Fantasy, MyFantasyLeague, Fleaflicker
 • X / Twitter — adds a value row under any tweet that mentions players
 • News &amp; analysis: <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/e4b1fe99d93467ab05ca5b6c753f597bd5b28ee96b767292e3ef8d8c1d8352cd/http%3A//NFL.com" rel="nofollow">NFL.com</a>, DynastyLeagueFootball, PFF, RotoWire, RotoBaller, NumberFire, CBS Sports, Yahoo Sports, The Fantasy Footballers, Draft Sharks, Pro Football Reference, NBC Sports, The Athletic, Reddit, <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/298d1ad25984469acf1bddd43be54fb6c4c923b3c372cb70ee4a63ef53cc79dc/http%3A//ESPN.com" rel="nofollow">ESPN.com</a>
