Undefeated season on the line

I like to stream defenses but I think the Vikings are a good ROS D but awful match up this week Do I drop them for a good matchup? Do I start them? Do I get two defenses?!

I would have to drop either M. Trubisky ( Winston owner), J. Richard, D. Martin aslo avaible are T. Smith and C. Sutton for another topic Which 3 should I roster and should I drop 1 for another D or just ride out a bad matchup
