ROS Stafford, Taylor, Cousins

I’ve been swapping Stafford and Tyrod in and out depending on matchups but now Cousins is available on the wire. I’m currently 4-4. I’m inclined to drop Taylor as McCoy and Benjamin are my starters and it might be too many eggs in one basket. The Bills have an awesome schedule ROS though so i feel pretty torn. I’d appreciate any tips or opinions. Thanks
