LeBron James is a nightmare on the basketball court. With strength that is equal to his court vision, James is undoubtedly one of the NBA's best of all time, and it has been that way for...quite some time. One team that has routinely been on the receiving end of James' terror is the Celtics, conference foes with LeBron for a decade and a half. With that extended tenure came some forgettable memories for Celtics fans.

Sorry, Paul Pierce -- here are James' most dominant career moments against the Boston Celtics.

3. Game 6 Victory in the 2012 Playoffs

LeBron earned his first ever NBA Finals victory in 2012 against the Thunder, but it would have never happened had it not been for an incredible Eastern Conference Finals comeback against the Celtics. Down 3-2, the Heat headed into Boston needing a huge road victory to bring the series back to Miami, and LeBron made sure that happened. With 45 points, 15 rebounds and an insane 73% shooting from the field, James delivered one of the greatest performances of his career, leaving Boston fans to remember this game with a shudder eight years after it happened.

In just his third year in the league, LeBron was already showing signs of greatness, nowhere more evident than against the Celtics. In his three games versus Boston that season, James averaged 38 points, 8 rebounds and just under 8 assists, culminating in a series sweep. James delivered 36 points in each of the two victories in Cleveland. But the headline by far was that year's double overtime thriller in Boston, where the Cavaliers pulled away behind James' 43-point triple double, with four blocks as well. This was James' best scoring season, and his games against the Celtics were a big part of it.

Beyond individual performances or series dominance, one of James' most memorable moments against the Celtics was his poster on Jason Terry. The monster dunk is one of James' career highlights, especially considering Terry's victory over LeBron with the Mavericks in the 2011 NBA Finals. That dunk aside, James had an incredible game in Boston with 37 points and 12 assists. Miami earned their 23rd consecutive win in the nail biter, with another Finals trophy coming LeBron's way that season.
