Brees, Stafford, Roethlisberger RoS?

Which two of Brees, Stafford, and Roethlisberger would you want for the rest of the season in a standard, non-keeper league? I currently have Stafford and Ben, thinking of trying to get Brees from a guy who just acquired Rodgers. Or should I just stick with what I have now?

It depends on what you would have to give up to get Brees. I would be fine with Ben/Stafford as my starting QBs but Brees will be better than both ROS
