In what aspect or area of life could you get away with treating *people* like this?
Why would it be allowed/condoned with a bunch of 12 year-old girls playing a sport?
Easy answer to this question was stated before: run.
There is a core of 4 or 5 players that will be carried. The new players are soaking up the playing time and are quite happy for now. They don't know the people that have been forced out and the team reputation hasn't gotten out to a wider circle just yet. Their children are playing and they are buying into the idea of building a winning program. They don't yet understand the cost. It won't be long before he grows tired of the new girls that struggle at the plate or in the field and they are quitely replaced.
