Yesterday was the NBA trade deadline, and a weird season got even weirder. The Brooklyn Nets’ owner, apparently acting out of frustration and pettiness, shipped his two superstars out of town and called it a day on the whole superteam thing. Russell Westbrook is now, finally, a man without a country. Various general managers threw all their future second-round picks on the table. A bunch of random players got sent to a bunch of random places. It seems like a great day for the Hold Steady, veteran rock poets of chaos, to release a new song called “Sixers.”
