I'm hoping for a Stastny bounceback, but I'm with CascadeFilly here -- Enstrom is considerably more valuable.
The additional name would depend on your roster I suppose. Hard to make suggestions with so little information.
Basically, Enstrom is still a top tier d-man. He's been good for 50 points in the past, puts up some PIM, and PPP.
Stastny has been middling the last couple years.
