Sure glad that no one complained about Bill's start. That was nepotism at work, too. He turned into the greatest coach of all time, but he had a lot of grooming for that role. I don't have a bit of a problem with him hiring his sons and teaching them the family trade.
Considering all the finds Bill has made in terms of coaching assistants (for example, Patricia, whose hire was about as off the grid as they come for someone trying to get into pro coaching), I'm surprised that people dislike that he's training the next generation. And, honestly, "the best person in the world" isn't always the best organizational or philosophical fit. At least here we can rest assured that Steven knows how his father thinks and works.
More sons should learn their father's trade. It used to be the norm. While I love having choice and freedom, I've always enjoyed working with my family on the few occasions that I've had that privilege. I worked some free lance with my parents for a while, and my brother and I started a business together, too. Great times.
