Chief Justice John Roberts might have popularized the metaphor of judges as umpires. But when talking about how judges can improve at their trade, Chief U.S. Bankruptcy Judge Mildred Cabán of the District of Puerto Rico and retired Minnesota state court Judge Kevin Burke embraced a different sports metaphor: the judge as an athlete. Cabán and Burke say that judges could benefit from the sorts of coaching relationships and intense review of past performance that athletes employ to improve their skills.
