Gregg Popovich has admitted that he has "no clue" which team will progress to the NBA Finals from the Western Conference.
The San Antonio Spurs have taken a 3-2 lead in the conference finals, but will be trying to clinch the series away from home against the Oklahoma City Thunder.
The Spurs coach told reporters: "I have no clue, honestly. I think every game, it's a different animal. It really is. We talk to our team about that all the time.
"You have no clue what's going to happen, how a team is going to come out, whether they're going to be lethargic or hold the ball, get 50/50 balls or don't get 50/50 balls."
The Spurs have led the series 2-0, but suffered back-to-back defeats earlier this week.
