And sorry, don't mean to dwell here, I'm just amazed that a "simple" job like coaching could be so time consuming.
Obviously you have never coached anything more than t-ball. There is so much that goes on everyday that you would never think of. Your playing mommy and daddy to anywhere from 15-75 kids. You are putting out fires everyday from everything you can think of. Then try and get all the logistical work, recruiting and writing or researching workouts done everyday. 60hrs a week seem realistic to me. I go to the office at 7am today and it is now 8:30pm and I still have some more calls to make.
