Is if the bigs on our team are incapable of shooting. We want their bigs to have to guard the perimeter/corners.
This way the paint is wide open and it will create either uncontested layups or wide open 3’s if the defenders have to leave their man to help out.
Penetration/paint touches is the key to getting open 3’s. Penetration doesn’t work very well when the team defending you has a big camping out in the paint - which would only happen if BYU bigs are incapable of spreading the floor.
