Depending on what flag you’re waving in this America’s Cup, today was either a massive victory or an enormous setback. Oracle Team USA, the Defenders of the 34th America’s Cup, suffered a bludgeoning on Tuesday and promised change. It arrived today in the form of an afterguard rotation. John Kostecki, the team’s ace tactician, stood down, replaced by Sir Ben Ainslie, history’s most decorated Olympic sailor. Unfortunately for Oracle, this change failed to alleviate their problems.
