The thing is, we discuss what we see on paper. But things may look different on the ice. What seems like a disadvantage, or "slightly worse on paper", may look totally different on ice. You see Ekman-Larsson-Karlsson against Suter-Carlson, or Hedman-Stralman against Niskanen-E.Johnson and say, hm, this one is better. But the thing is, these players won't face each other, not directly. They will be facing the other team's forwards, not defensemen. Suter and Carlson will play Backstrom and F.Forsberg, for example. Hedman and Stralman will play Backes and Oshie for example. So, it doesn't really matter that much who's defense is better on paper, it's who's defense will be more effective on the ice. And on the ice, Ryan Suter might do a better job against Nicklas Backstrom or the Sedins, than Hedman against Kane and Pavelski, you never know what happens. Hockey is a game. It's not math. Anything can happen. Hit happens, turnover, and from an innocent situation you go 2 on 1, or 3 on 1, a couple of bounces in front of the net, etc, etc.
