A fight between two animals: dogs; lions; mixed martial arts foes; is usually preceded by circling. I’m no expert on this - I don’t much like violence. But the idea behind the circling seems to be: let me see how you move. Let me see if you can be caught off guard. Let me see if I can detect fear in your eyes, and then strike at you when you decide to be a bit defensive.
Colorado and LA have done the circling for this season, and now each of us know what we’re getting if and when there is another dogfight.
