I think its gotta be the Celtics especially after game 7 the year before. Red Sox fans had to deal with Yankee fans for sooo long. Also, as much as I appreciate the Lakers Celtics Rivalry, we only see them twice a year during the regular season. We see the yankees about 21 times a season and it was also the same year as the v-tek A-rod fight. I think in addition to the team rivalry, the underlying stories like the nomar trade, and curts sock, just made that season so much sweeter.
