The regular-season rivalry wasn't very much of a rivalry, as the Celtics won all four matchups. Boston won the first three games by 23, 27 and 13 points, respectively, before taking the final showdown, 119-117, in overtime back on April 8 in New York.

If you want to be there — at either Boston or NYC’s Garden — tickets are available for all seven hypothetical games. At the time of publication, the lowest price we could find on tickets for MSG games was $368 before fees on Vivid Seats. Tickets start at $228 before fees in Boston.
