I don't know about D3 but if there is a shortage of fastbreak or pressing teams in D1 you can trace it back to when WIS decided to punish coaches who used those sets by exaggerating the fatigue factor back around season 30 or 40. I had teams who were serious contenders completely destroyed b/c admin decided pressing for an entire game was unrealistic. They backpedaled 3 or 4 years later, but most pressing/fb teams had been forced to change.
