I haven't seen it mentioned here, but it's been in the news how in the 4th quarter, whenever Duncan got the ball posted up against Dirk, Avery yelled from the side "Double! Double!"
That cause Duncan to hesitate and wait for a double team instead of taking it right at Dirk.
But the double never came, Avery was tricking Duncan with his yells.
Of course being out of sync, Duncan didn't score against Dirk after being fooled like that.
It was great gamesmanship. I wonder why he didn't save it for the playoffs, Duncan won't likely fall for that twice.
