Guys, just be okay with the fact that we disagree.
Most of the circular arguments that go nowhere on this site are, ultimately, about people's opinions on players. And, sometimes, the differences between 2 players are small enough that it'd be simpler just to say, "yeah, they're both good, so just move on with your life." It comes down to opinions that are subjective and not easily comparable (e.g. liking smooth-skating defenders vs. ones that throw hits).
But there are some opinions and stances that are based on incorrect facts, and operating under those opinions typically gets people into trouble. In this case, you assert that Dustin Byfuglien is, at best, a third-pair defender because he wastes most of his time hitting and does nothing else. The concept of pairings is generally accepted by most to be predicated on point production, and Byfuglien's very high point production stands in stark contrast to this label of a 'third-pair defender.' And the claim that he does nothing else besides hits implies that he does no useful things, which has already been shown to be false by his point production, which people generally accept as a 'useful thing,' because points are the ultimate objective for most players, and goals and assists win games.
I'm mostly just doing this to try and help you understand that you need to be able to gather and verify facts about a hockey player before you begin to evaluate them. I assume that you can do the same in real life, where, when presented with a situation, you can evaluate it properly and come to a conclusion based on correct facts. It shouldn't be too hard to extend that skill to hockey players.
