One of the huge keys to Team USA's success in this Olympic basketball tournament is that the tempo of every game changes when Deron Williams and Russell Westbrook come off the bench. This time, though, it's Spain's backup guards that have made a huge difference.
Why is Spain ahead? They have Sergio Llull and Sergio Rodriguez to thank. Both have played really well in this second quarter, pushing the ball and pressuring Team USA defensively. More importantly, they've generally taken good care of the ball, preventing Team USA from getting out in transition.
