NBA's Brandon Jennings -- Religious Players Are More Successful

Sorry atheists ... NBA players who have a good relationship with God are more successful than NBA players who don't ... so says Detroit Pistons point guard Brandon Jennings.

Jennings was at LAX today when he told us religion plays a huge role in the NBA ... "Before every game we always have a little bible study ceremony ... any city you go to, so it's pretty cool."

That's not the case with every team -- Doc Rivers, in an effort to respect different beliefs, reportedly does not allow team prayer in the Clippers locker room ... though he does lead a moment of silence before games.
