With Mrazek getting extended and looking by and large better than he has in recent seasons, I have concerns about Soderblom. Then again, Mrazek does get hurt and he's not being paid so much as to be unable to be pushed aside. If Hart is looking at major issues due to 2018, Peterson's value rises from a virtual zero to....well.....more than zero. But he's looked worse and worse with each passing season. I'd gamble on Soderblom of the two. Cossa is a nice piece to own, with Detroit's netminder situation up for grabs and Cossa, despite being only 21, already seeing action in his second AHL season.
