Stony Brook looked like well oiled machine. Top players are expected to perform and stay on the field- especially attack sharp shooters. The best high school coaches adhere to this, and reprimand selfish players who don't understand the game. It's a quick transition, not like soccer. My brother is a Hs coach and does not necessarily like his best player-been on varsity since 8th grade and has a chip on her shoulder. Committed to an up & coming D2 school despite D1 offers. But he knows she will leave everything on the field, and wants the ball in her stick when game is on the line. I keep telling him you never know what goes on at home, could be a sad or bad situation so try and praise her and value her. Girls remember that stuff and respond to it. High school coaches need to follow the Gait/Spallina/Levy role. Leave personal feelings out of it and depend on your leaders, reward them with praise not politics.
