They're going to keep playing, man. Even if they don't knock down shots they're going to get 2nd chances, crash the boards, rebounds, find the open man, get to the FT line, move the ball, get the ball to Bam. Try to execute from there. They're going to play hard, they have guards who can penetrate/drive and kick/that's what they do. It has to be constant pressure.
