Excellent points. The comparison to fast-break basketball is an apt one. I was a Phoenix Suns fan for a long time. I watched year after year of them living and dying by the fast break. Pretend as if you have a 15-second shot clock. It was fatal for them. The game changed. Players got more agile. Defenders became too quick and able to guard in transition. Fast break basketball -- while exciting to watch -- quickly became a low percentage strategy. The same with net play in tennis. It is very exceptional and situational when it can be used successfully. But as a primary strategy -- not going to work.
