Best players need to play in right combo
Not a fan of 5 in..5 out
I am fine with it to start the game.
It gets everyone involved and invested in the game.
Once players begin to tire at various stages due to different conditioning levels, or if players get into foul trouble, then you have to go with different combinations.
Also, if 1 player is so much better than everyone else (Baylor transfer?), I would play her for longer stretches.
In the Purdue game, I thought it was effective because they use so few players, and I think a team like that will wear down at the end of the game (like a boxer taking body blows all game).
It has to be discouraging seeing wave after wave of fresh players come in.
It’s probably not as effective against deep teams, or teams with great ball handlers (obviously).
