LeBron shifting to playoff mode

Now he's got to get the Cavs to, ahem, follow him.

Following a personal rite of spring he began several years ago, LeBron James has begun preparing for the upcoming NBA playoffs by limiting his access to social media in order to avoid outside distractions as he and the Cavaliers make another run at an NBA title.

James, who has coined his social media blackout "Zero Dark 23", took some early steps toward sharpening his focus by unfollowing the Cavaliers' account - and those of some media members - on Twitter.
