ESPN, CBS and FantasyPros all produce fantasy football cheat sheets that are accessible in the respective website's fantasy football section. Cheat sheets are available for preseason rankings, weekly rankings by match-up and for daily fantasy as of 2015.
ESPN's sheets are located by hovering the mouse over the Fantasy button in the top right corner of the page and then clicking on the Football button in the pop up menu. ESPN creates downloadable cheat sheets with player rankings based on the scoring format (standard or point per reception) and draft format (standard or auction). Sheets are available in both a positional breakdown format and a top 300 player format.
CBS' sheets are located by clicking the Football button at the top of the Fantasy page, and then clicking on the cheat sheet article for the current week of the NFL season. The sheet separates players by that week's games and highlights the fantasy relevant players in the match up.
FantasyPros creates cheat sheets for various daily fantasy sites such as Fanduel and DraftKings. Locate rankings by hovering the mouse over the NFL button at the top of the page, and then hovering the mouse over the Daily Fantasy option in the pop up menu and then clicking on the Cheat Sheets option in the new pop up menu. Rankings are subject to change throughout each week, depending on player news that is released by teams.
