The duration sounds about right to me- my dad played soccer when we were young and was gone up to 15 hours a week, on top of a 55 hour work week.
Then he became a coach and was gone up to 25 hours a week on top of a 55 hour work week.
It drove mum nuts. He took a year off it- both playing and coaching- and was so miserable and grumpy that mum forced him to go back.
ETA: mine doesn't play thank god- as the kids' sports take up more time that his would lol
