LeBron James Shows Off Incredible Memory Recalling Cavaliers vs. Celtics Sequence

The Boston Celtics cruised to a 108-83 victory over LeBron James and the Cleveland Cavaliers in Sunday's Game 1 of the Eastern Conference Finals, and a 7-0 spurt to start the fourth quarter helped them push a 14-point advantage to a more comfortable 21.

The seven points came from a Marcus Morris dunk after an offensive rebound, three-pointer from Marcus Smart and layup from Jayson Tatum, which James recited from memory after the loss:

While he may not have impressed on the court with 15 points on 5-of-16 shooting from the field and seven turnovers, the four-time MVP showed off his basketball IQ by rattling off the critical sequence without much hesitation.

Boston faced little resistance during the Game 1 victory, but the fact it responded to Cleveland's one stretch of momentum by putting the contest away to start the fourth quarter is surely encouraging for it heading into Tuesday's Game 2.

Despite facing a 26-point halftime deficit, the Cavaliers won the third quarter 29-17 and had the fans at TD Garden nervous entering the fourth. However, the Celtics responded with the quick 7-0 burst that James recalled in impressive fashion and never looked back in the easy victory.

Even with impressive offensive performances from Jaylen Brown (23 points and eight rebounds), Marcus Morris (21 points and 10 boards) and Al Horford (20 points, six assists and four rebounds), the Celtics' defense set the tone, as it has all season.

Head coach Brad Stevens' club was best in the league in defensive rating in 2017-18, per NBA.com, and clogged James' driving lanes while contesting the majority of his looks.

The result was a dominant defensive showing, something the Celtics will likely need to replicate a number of times throughout the rest of this series if they are going to eliminate the three-time defending Eastern Conference champions without a healthy Kyrie Irving or Gordon Hayward.
