VIDEO: LeBron gives up on defense, concedes 3-pointer
Against the Los Angeles Lakers on Thursday, he essentially conceded a corner-three to Wesley Johnson, who's fully capable of knocking down threes (37.1 percent). James even started leaking out with Johnson's shot still in the air.
James did revert back to his defensive ways in the postseason last year, so the Cavs will just have to hope the same holds true this year.
Then again, the Cavs obviously can't afford any defensive slippage from LeBron given their current position, while the Heat were able to.
