Fantasy football sit-and-start advice should always be relative and league-dependent. Note that some players are targeted for DFS. Good luck with your Week 15 lineups!
Start: Michael Pittman
The Vikings have allowed the most YPA, the most passing yards and the second-most fantasy points to wide receivers this season. Pittman has enjoyed his best fantasy games this year when Matt Ryan starts, so consider him a top-20 WR this week.
Thielen has scored in two of the past three weeks but has yet to reach 75 receiving yards in a game this season.
