Joey, Callahan, and Washington are about as experienced a Finals crew as the league could reasonably put together for a game this early in the series. Joey will work his 49th Finals game tonight (for sake of comparison, the other 11 Finals officials this year have worked a cumulative total of 96 Finals games over the courses of their careers; if you take Danny Crawford out of that, the other 10 Finals officials have cumulatively worked 66 Finals games (or only 17 more than Joey has by himself)). Callahan has called at least one game in all but one Finals since 2003 and 15 Finals games total. Washington is working his 4th Finals since 2008 and is working the 4th Finals game of his career tonight.
