Tristan's Keeper Top 250 has been updated through March 24.
Tristan's Keeper Top 250 is based upon a player valuation formula that accounts equally for the next four seasons, as well as the fifth and beyond:
2016 performance: 20 percent
2017 performance: 20 percent
2018 performance: 20 percent
2019 performance: 20 percent
2020 performance and beyond: 20 percent
Position eligibility is determined based upon a minimum of 20 games, otherwise the position the player appeared at most in 2015. Players' listed ages are as of Apr. 1, 2016.
Players' September 2015 ("Sept. 2015") and peak rankings in past keeper lists ("Prev. Peak") are also provided: These lists have been published semi-annually from 2010-13 and tri-annually since 2014, with "Pre," "Mid" and "Sept." designated to differentiate whether the rank was in the Preseason, Midseason or September lists of those years. For example, Justin Upton is listed with a peak of 3 in "Pre-2012," meaning that his best all-time rank was third overall, in the February 2012 list. A "-" means that the player has never been previously included in a Keeper Top 250 list.
