Looking at the schedule Dubnyk and Kipper have 5 starts left total, no back-to-backs and 1 game vs. each other. I'd say they get all 5 starts and end the week with 4 wins total.
Also looking down the schedule Minnesota plays St. Louis Sunday. I'd sit my guys down and see what happens. If his goalies get the wins (to 3 or 4 total) but you keep a healthy lead in peripherals you can try and lockup a sweep Sunday, if its too close you can bench your guys and keep the points you have and obviously if he never catches you bench them all week.
