I think the Blues would really benefit from RNH as he's a top 6 center that would probably thrive in an environment where he's playing with top 6 talent. The Blues are going to need a replacement for Paul Stastny as he's getting older. Edmonton would probably benefit because the Blues have too many 3rd line centers and they come at a fairly cheap cost. Not to mention the Blues can probably give Schmaltz to sweeten the deal. RNH to St. Louis for Berglund or Sobotka, Schmaltz, 2nd. The Blues can probably add Carl Gunnarson as well to make the math work for this season too.
