One of the biggest challenges which the Boston Celtics will face in the Eastern Conference Finals series against the Cleveland Cavaliers is LeBron James. They'll need to figure out a way to deal with his threat on the court.

James is able to turn things on in an instant to help out his Cavaliers when they need him the most, as we have seen him perform late on in games several times in this year's playoffs already. Throughout the postseason this year, he almost has a triple-double average, as he averages 34.3 points, 9.4 rebounds, and nine assists per game.

However, things are a lot different on the court for the four-time MVP winner when he is marked by one certain Celtics star, and it will be interesting to see if Boston's head coach Brad Stevens utilizes him in this way.

During his last 11 regular season and playoff games against a team which had Marcus Morris, James has averaged 21.1 points per game while shooting just 16.3 percent from 3-point range, and he did not reach 30 points in any of those matchups either.

Stevens, however, has said while Morris is successful when it comes to defending against the Cavaliers star, his whole team must guard against him in order to make sure he doesn't play a huge impact on the game.

Stevens said to NBA.com: “It’s totally a collective effort. Marcus is big, strong, competitive guy, but you have to guard LeBron as a team.”

As for how Morris is so successful when it comes to guarding against James, the man himself believes it's down to his size.

Morris said: “My size. I’m 6-9, 240. I think that’s the perfect size to guard a guy like that who’s probably like 6-9, 260. So just having the height, the length and having the power, too, that all helps.”

During their last matchup on February 11, Morris guarded James on 30 possessions and allowed just 13 points on 36.4 percent shooting from the field. He wouldn't mind another performance like this throughout the series.

The Eastern Conference Finals series between the Celtics and the Cavaliers begins tomorrow with Game 1 taking place at the TD Garden in Boston.
