Everything happens for a reason. Or—more accurately—innumerable reasons, many of which will never be fully understood. When something bad happens (for example, a quarterback doesn’t perform well against an insufferable rival and a team loses) everyone reacts differently. Some people want to understand as many specific reasons as they can so they can make unbiased opinions about which are likely to become patterns, which might change over time, and which are so random they can be dismissed. Those people are definitely nerds and possibly robots.
The rest of us either come into the game with our minds made up and focus on the things that confirm our opinions or we form an often-emotional gut reaction at some point in a game and then notice the things that confirm this reaction.
