The NCAA Tournament the NBA playoffs are not. Remember the first day of the 2015 Big Dance with all those upsets (things were mostly chalk after that)? Well, that can happen in a single-game elimination format but not in a best-of-seven series. Three teams now hold a 3-0 lead in the first round of the NBA playoffs, and four more teams have the chance to grab a 3-0 lead starting Friday. This could be the most lopsided first round since 1983-84, when the NBA moved to a 16-team playoff format.
