If that was the case, why didn't all the "better" defensemen on the Columbus Blue Jackets have a better +/- than him.
Now, +/- doesn't mean everything, but I think it says a lot when a guy like Goloubef (or Dano) has that much better of a +/- than the other guys. Also, you made the claim that his +/- was only good because he was playing with better players. So, if that is the case, why aren't theirs better or at least as good as his? BTW, he was a +9 in the AHL in 2013-2014 and 2012-2013. So, for the last 3 years he has been a plus player in the AHL and NHL.
Goloubef = +12
Tyutin = +8
Connauton = +1
Murray = +1
Savard = +0
Wisniewski = -10
Johnson = -13
Prout = -14
