As Miami Heat take the lead in the race for the NBA Championship, Ed Wyatt questions whether they have enough killer instinct to take out the title.

As I suggested, the Miami Heat were too good for Oklahoma City in Game Three of the NBA Finals.

LeBron James scored 29 points and Dwyane Wade added 25 in a 91-85 win that gave the Heat a 2-1 lead in the best-of-seven series.

With two more games in Miami, the Heat can clinch the title with wins in Game Four and Game Five and avoid a trip back to Oklahoma City.

But do they have the killer instinct to put the Thunder away?

LeBron has been criticised for failing to deliver in the clutch, but now he's got an opportunity to prove his doubters wrong.

Miami's defense was superb on Monday. The Thunder couldn't get the shots when they needed them, and even though Kevin Durant (25 points) was effective again, he was limited by foul trouble in the third quarter.

So now we have Game Four, which I think is a must-win for Oklahoma City. If the Thunder lose and go down 3-1 with Game Five in Miami, it's all over.

Durant should continue to get his points, but Russell Westbrook (8 of 18 from the field in Game Three) and James Harden (a dreadful 2 of 10) will have to step it up, and the team will need to show some more confidence in crunch time. The Thunder are a young team compared to the Heat and their inexperience showed in Game Three.

Miami is far from invincible. The Heat turned the ball over nine times in the fourth quarter and made several poor plays late in the game that could have been disastrous.

Bottom line?

I still feel strongly - as I have all along - that the Heat will win the series, but I think it's well worth considering Oklahoma City @ Betfair odds of (2.50) to come out on top in Game Four.
