"It's a rivalry?" Paul Pierce's words, not ours. With the Celtics maintaining their dominance over the Atlantic Division for so long, it was the New York Knicks who fell off the NBA radar and needed something to revive both the team and the city. With the signing of Amar'e Stoudemire over the off-season and the acquisition of Carmelo Anthony during the season, the Knicks are back in the playoffs for the first time in seven years. Fittingly, this Sunday at 7 p.m., New York will face Boston in the playoffs for the first time in 21 years. In anticipation of their upcoming Eastern Conference first round match-up, we give you 8 Great Moments in the Celtics-Knicks Rivalry. Yes, the rivalry is back, baby! Yup, we're turning our Dick Vitale swag on.
