I dunno, Benning has been a plus player every year(yeah I know a flawed stat) but honestly he has done that with so many bad teams here, I am not saying Benning is all world but he is not the dumpster fire many think he is. I just know that with my own eyes that Russell has been a liability out there this year, unless Benning is there with him.
When I say "stabilize" I don't think it is really anything to do with Benning, I think Russell simplifies his game with Benning is all, with Klefbom I had the feeling that Russell felt like he had to try to move the puck like him, not his strength. With Benning his routine is "get the puck out and keep it out of the net". He is far more suited to a bottom pair with the right partner at this stage. I would not be opposed to Larrson playing the bottom pair with Russell when he gets back.
