NBA Star Russell Westbrook -- NBA Blasphemy ... He Didn't Watch Game 7!

NBA stars have much better things to do with their time than watch the NBA Finals ... so says OKC Thunder point guard Russell Westbrook -- the second NBA'er to admit missing what the rest of America watched.

Russell (who missed most of the playoffs after tearing his right meniscus) was out in L.A. Friday when our photog asked the All-Star (who was walking without crutches!) what he thought of the Miami Heat's epic win in Game 7 of a nail-biting series.

But Russell -- just like fellow b-baller Dwight Howard -- says he didn't bother to watch the game!
