The 12 best NBA playoff rivalries of all time

Lebron James' arrival in the NBA in 2003 was announced as a wax change. However, the old guard was not yet ready to be replaced.

James and the Cleveland Cavaliers never made it to the mountain peak during his first stay. The Boston Celtics were most common during their five post -season.

In 2008 James met three in the semi -finals of the Eastern Conference against Boston's Big. He scored an average of 26.7 points per game and won the Cavs with 45 points in game 7, but Boston's deeper talent won.

A second matchup between these two teams in 2010 could be attributed to breaking up the CAVS. After Cleveland lost three games in a row to fall 4-2, James finally decided to bring his talents to South Beach and to join the heat.

From this point on, James' after season with the Celtics always went on the way.

Whether with The Heat or Back with the Cavs, James won five series against Celtics (2011, 2012, 2015, 2017, 2018). The only thing that really came nearby in 2012. In this final of the Eastern Conference, the Celtics rose from a 0-2 deficit to achieve a 3-2 lead. James reacted in game 6 with 45 points on the street, and the Heat claimed game 7 on the way to the title – James' first.

In total, James achieved an average of 29.6 points, 8.5 rebounds and 6.3 assists in 41 playoff games against the Celtics.
