Fantasy football cheat sheet: Start, sit and more tips for Week 15

— --

Anyone with Thomas Rawls or Todd Gurley starting on their playoff rosters this week couldn't have been pleased with the way the Seattle-Los Angelees game went on Thursday night. Rawls had nowhere to run all night and settled for 34 yards on 21 carries. Gurley wasn't much better, carrying 14 times for 38 yards in a game Seattle won 24-3.

Looking closer at the matchup, however, it was pretty clear entering Thursday that Rawls and Gurley would have a difficult time finding running room in a physical type of game with two struggling offenses.

We're well past the time of year when players should earn spots in your lineup based on name recognition. It's the fantasy playoffs, and the matchups and recent production matter more than ever before. Just ask anyone who waited 15 weeks for Gurley to get going.
