This week the defensive streamers aren't too great so if you don't get the first option then just make sure you prepare your bedroom for a good crying session.
The Redskins get a matchup at home to the Browns and they are a much better defense so they should put away the Browns in a much better fashion than the Dolphins.
I know you may not be able to call the Texans defense a streamer but it is possible that they were dropped in your league after JJ Watt went to IR. I would pick them up if they were dropped and use them at home against the awful Titans.
It hurts just to write this but the Jaguars might be a good streaming option against the Colts. Indy has given up the 4th most points to opposing defenses so far. The offensive line is bad and the Jags defense should be able to get some sacks. The risk is that Blake Bortles shits himself during the game or Andrew Luck just demolishes them... So yeah it's kinda scary but sometimes you just have to say, fuck it.
On the other side you have a decent streaming option in the Colts. Technically the Jaguars are playing a home game but they will be playing in London early in the morning. If Blake Bortles does what he does best then the Colts defense could pay off big for you. The Jaguars are allowing the 8th most fantasy points to opposing defenses.
