In over half of the Columbus ACGM's I've seen, Wennberg has been bought out. If he is, we should absolutely try to sign him. He has good chemistry with Saad, he is defensively reliable, and can provide some offense as well. Perfect 3C at the right cap hit.
At this point, Strome and Nylander are worth more for their trade value than their on-ice value. Let's get something for them while we still can.
Robertson is a prospect I've liked for a really long time, and he's the type of D prospect the Hawks don't have (big, reliable, and tough to play against). I'm willing to potentially downgrade the pick if need be, but I think Robertson is expendable to NYR since they would have Lindgren/De Haan/Miller/Hajek on the left side for the future.
After next season, they should protect Toews, Kane, Cat, Saad, Keith, Seabs, Brodin, Murphy, and Crow, then hope Seattle takes Maatta, or pay them to (they would need to clear his cap). With Maatta gone, they should have the cap space to re-sign Saad and Brodin, as well as Suter.
