AS an ex-teacher, I can only but agree with you. I am uncertain if philosophers make the best kings, but am certain you are right in believing that teachers make the best coaches.I talk a lot of shit.
But I get the impression that the previous coaching group didn't do much differentiated instruction, because obvious weaknesses never changed. I like that we've got a trained teacher in charge. Clarko's brother is a principal. I worked under him for a while - his cliche use is world's best, but Clarko hired assistants with teaching experience and his players continually improved in a way that ours didn't.
