Cleveland Cavaliers have won all four games this postseason, and they became the first team to sweep their playoff opponent. The defending champions faced the Indiana Pacers in the first round and they swept them, thanks to the fantastic performances by LeBron James.

After four playoff wins, James set a few more records, proving that he is still the best player in the league. Cleveland Cavaliers are on a mission to defend their championship title, and their postseason couldn't have started any better. Right now, they have a lot of time to rest as they are waiting for their second-round playoff opponent, which will be a winner of the Raptors-Bucks series.

LeBron is the king of playoff sweeps

Thanks to the sweep against the Indiana Pacers, LeBron James set the record for most playoff sweeps with ten. Prior to the series, James was tied with Tim Duncan in this category, but he set a new record last night. Beside two of them, Tony Parker and Manu Ginobili, who have played for the San Antonio Spurs with Duncan, take the third and the fourth spot on the list.

Furthermore, LeBron James set the record for most consecutive first-round wins with 21.

James passed Magic Johnson, Michael Cooper and James Worthy in this category, taking another number one spot when it comes to playoff achievements. Last time James lost a first-round game was in 2012 against the New York Knicks. LeBron was a member of the Miami Heat back then, and the Knicks won game 4 by two points.

James was impressive in the first round

Cleveland Cavaliers have been the best playoff team so far in the season, and LeBron James has been the best player, without any doubt. James averaged 32.8 points, 9.8 rebounds and 9.0 assists per game in the first round, and he shot efficiently from the floor, converting 54.3 percent of his shots and 45 percent of three-pointers.

Beside nearly averaging a triple-double, James was the best player of the series by a wide margin, and the Cavaliers outscored the Pacers by 28 points with him on the floor. Additionally, James did a great job on defensive end of the floor and averaged 3.0 steals and 2.5 blocks per game. He played a big role in limiting Paul George, the best Pacers player, which allowed Cleveland to win games more easily, and sweep their first-round opponent.

LeBron James has been nothing but impressive this season and if he keeps it up, we might witness one of the all-time great playoff runs.
