Easy to say when you're not in that situation. Everyone thinks money can make everything tolerable. Well sorry, but glad you aren't a coach because you'd be in for the wrong reasons. Do people really think that coaches do what they do because of the money? They don't. They love the game, know the game, and can't play anymore. The closest thing they can get to that high is coaching. Sure money helps, but its not the backbone of what they do
But they should also know this comes with the territory and help their family understand that as well. If this isn't a death threat or some credible threat of bodily harm, then somebody either needs to learn to let things roll off their shoulder or find another profession.
