There's such a difference between trying to be right and trying to understand. It's just two different ways to use the board.
A team you follow closely makes a move that doesn't seem to make sense. I think we can all agree that Belichick and the staff know more about football than any of us, and certainly more about their systems and what they are trying to accomplish.
Person 1 assesses it and makes a pronouncement - it's stupid, etc. Person 2 looks at it to try to figure out what the team is doing, because what you're seeing doesn't add up. Person 2 might throw out several theories and seem to change their mind as they assess and look at it from different perspectives.
Interestingly, if Person 1 and Person 2 do this consistently, Person 1 will generally be right a higher percentage of the time. Some moves work, others don't, but by taking one position and sticking with it rather than exploring a bunch of possibilities, explanations, what is planned, you're right sometimes and wrong sometimes. Person 2 is throwing out a ton of theories, some of which are thought out and others that are quick takes and what ifs, trying to understand the moves of experts in their field with track records of success. Most of them are going to be wrong, especially when the moves tend to be non-conventional. And Person 2 will also appear wishy washy, taking multiple sides of various issues.
Generally speaking, Person 2 might be considered thoughtful, but they will also tend to be considered a fanboy, and accused of always rationalizing any moves that are made as they try to find the logic and the plan behind the moves.
On the other hand, Person 1 may be considered a curmudgeon or a hater by a passionate fanbase, but they will also be considered an independent thinker because they don't always explore looking for the underlying logic/strategic benefit of a move if it's not immediately apparent.
But who brings more to a discussion board? And who learns more?
I think the Planet is fracturing right now, pretty much along those lines, combined with some basic civility. We've had trolls come and go, but this is the extended period I can remember when I haven't felt like this place is a refuge.
