What do I do with this roster?!

I am currently on a 4 game losing streak and sit at 2-4. My roster is:

Matthew Stafford
DeMarco Murray
Lamar Millar
Julio Jones
Kyle Rudolph
Duke Johnson
Joe Mixon
Ty Montgomery
Pierre Garcon
Randall Cobb
Jason Witten
Wendall Smallwood (who I am dropping because Stafford is on a BYE)

Do I need to trade for someone? Keep going forward and pray that my players perform? This has been one of the more interesting seasons in this 10-man league as I thought this roster would be ELITE. Thanks Footclan!
