Hate to say this, guys, but it's mainly up to us as regular users
to take the game-thread back where we want it to be, since there's not much we can do as moderators.
You all know how much of a slippery slope it is, moderating heavily opiniated, adrenaline filled threads. There's little difference between a single "Oh man Tony Allen sucks!" post and fifty "Doc Rivers should be fire, we're going to lose" posts.
We can't "make people post constructive criticism", or turn them into professional analysts. That's something we'll have to do ourselves by setting the bar high for our own posts.
And if you have some knowledgable friends, people that know their basketball and know how to think objectively, bring 'm in! Spread the word! Rally for the cause!
Set the example, raise the bar, tell a friend!
