LeBron Sets a Screen on His Own Teammate?

Yesterday the Cleveland Cavaliers and Miami Heat faced off in a preseason game.  During the first minute of the game LeBron decided to run the pick and roll with Norris Cole.  Wait.  That's right LeBron set a screen for his ex-teammate.  He soon realized he is on the Cavs now, not the Heat.  It looks like it's even taking LeBron a little while to adjust from Miami to Cleveland.
