Oh, and while I'm at it, IN: college coaches care about grades because they have to (not necessarily because they want to) - they cannot risk loosing a scholly because of a low APR. Kids with poor grades put them into bad spots. Players must be able to maintain whatever the academic rigor of the college presents. If they cannot, they cannot play. If they cannot, colleges risk not meeting their APR. Coaches lose players and schollys. A bad, bad thing.
And if you don't think this year's compressed schedule impacted the academics of even the most academically gifted players, go find one and ask them. It has.
