LeBron James has shifted into playoff mode, explaining his recent purge on Twitter that eliminated the Cleveland Cavaliers from the accounts he's following.

"I have (changed his focus), a little bit sooner than normal, but you know I understand that it's right around the corner and I want to start mentally preparing myself for the distance," James said after the Cavs' practice.

James unfollowed the Cavs' Twitter account Monday and then declined to explain why.

James has been quieter than usual in recent days.

"I'm just being a little more sharper minded as of late, just gearing toward it," James said. "Understanding that it's right around the corner and it's going to be very, very challenging."
