Black or white. Positive or negative. Good or bad. Up or down. Sports commentary is merely an opinion, offered from a certain perspective.
Good people can disagree.
The world would be far less interesting if we all thought the same way. We disagree with our parents regarding who should be president. We disagree with our spouses over what color the bathroom should be painted. We disagree with our golfing buddies over who is the best money player. It's only natural we should disagree about whether a coach's decision was boneheaded or a referee's call was biased.
