context: The Orlando Magic (making their first ever NBA Finals appearance) began the 1995 NBA Finals at home, hosting the defending champion Houston Rockets. With the Magic up 110–107 late in Game 1, Nick Anderson missed four consecutive free throws in the closing seconds of the game, and Kenny Smith hit a three-pointer, tying the game and sending it to overtime as well as setting a new record with the most three-pointers in an NBA Finals game with seven. The more experienced Rockets went on to win in overtime and eventually swept the Magic, winning their second consecutive NBA Championship. In achieving this, they earned the distinction of being the only team to win both championships during Michael Jordan's first retirement (although Jordan did return in the closing months of the 1994–95 season), as well as the only one outside Chicago to win multiple championships in the 1990s.
