Ward is doing awful and at this point I would consider going elsewhere with him. Varlamov is a must drop, that guy couldn't put up consistant numbers to save his life.
Backstrom has way higher potential than Varlamov. I would definatly make that move.
As for Ward, hold on to him a little longer, he may turn it around, and his back ups arn't good enough to steal much time from him.
If you can, maybe pick up a 3rd tender in Scrivens until Reimer is settled back into his role. I see Scrivens playing a lot if he stays consistant. Also on a young team, Dubnyk is definatly work a look. His numbers are strong, this is his first real kick at the cat, so I would definately pick up Scrivens until Reimer returns, then roll Dubnyk.
