David Blatt made two potentially disastrous coaching mistakes in the final seconds of the Cleveland Cavaliers' 86-84 win in Game 4 at the Chicago Bulls.

Blatt attempted to call a timeout, unaware the Cavaliers were already out of timeouts.

Blatt's assistants, most notably Tyronn Lue, pulled him off the court as he was attempting to walk on the floor to call the timeout.

After the ball went out on the Cavaliers' baseline and the play was reviewed, Blatt originally drew up a play that would have had LeBron James take the ball out.

"There was doubt at first," said J.R. Smith.

James overruled Blatt wanting the ball.

"To be honest, the play that was drawn up, I scratched it," James said. "I just told coach, 'Just give me the ball. We either going to go into overtime or I'ma win it for us.' It was that simple.

"I was supposed to take the ball out, "I told coach, 'There's no way I'm taking the ball out unless I can shoot it over the backboard and go in.' So I told him to have somebody else take the ball out, give me the ball and everybody get out the way."

The playcall ended up having Matthew Dellavedova take the ball out and James' flashed to the corner for a buzzer-beating shot from the corner.
