Know Your Foe (KYF) is a long-running (since when?) feature on Purple Row dedicated to educating users about the Rockies' upcoming opponent. One of these is released for every series the Rockies play, including one for each series the Rockies play against a divisional opponent (making 6 in total against said foe). KYF goes in-depth to the opposing starting pitchers the Rockies are going to face in a series and also lets readers see how an opponent has been faring heading into a series with the Rockies.
