Spurs have stars, but it's the role players who have helped put Heat on the NBA Finals ropes

If the polling for NBA Finals MVP was being done before Game 5, no one from the star San Antonio trio of Tony Parker, Tim Duncan or Manu Ginobili would have led the balloting.

That would sound like a good sign for the Miami Heat.

It's not — not with the way Kawhi Leonard and Boris Diaw are playing for the Spurs.

They are role players in name only. Leonard has led the scoring charge in the last two games and Diaw has more assists than any other player in the series. They're a big reason why the Spurs can wrap up a championship on Sunday night, when they take a 3-1 series lead into Game 5 of the finals.

Leonard averaged 24.5 points on 68 percent shooting in Games 3 and 4. And in the Spurs' three wins, they've outscored Miami by 65 points with Diaw on the floor.
