screwball-
you should expect the HS coach to teach your kid the objectives that should be taught in the classroom - that is his primary job... teach basic fundamentals on the field.
unfort. too many coaches (of major sports) get the boot because of W/L record and not how great of an educator/mentor they are... there is hardly a parent out there that wants to know how well the HS coach teaches is class...
of course, that is our society...
