It's one of the most important weeks in fantasy football -- the first week of the playoffs (for most leagues). There's no room for error, and if you make one start or sit error, you can wave goodbye to your season. And even if you are one of the owners lucky enough to secure a bye, you shouldn't quite sit back and relax all weekend; now is the best time to make moves in advance of next week.

Fantasy Football Cheat Sheet: Don't count out Eagles' offense in Week 14

​There are several injured players that could impact fantasy lineups this week. Cardinals WR Larry Fitzgerald should be back in the game after missing the last two weeks, but is he worth starting in the uber-important first week of fantasy playoffs? Giants RB Rashad Jennings is struggling with ankle discomfort, so should owners start him against the weak Titans rushing defense? RBs Justin Forsett and Isaiah Crowell have made their way into fantasy lineups this season, but both are game-time decisions. Again -- start or sit?
