So many of the best coaches in the game today have coached their sons not only in youth/middle school but also in high school and even college.

Look at the MIAA "A" Conference and almost every team has a head coach or assistant coach with a son on the team including at least the last four league champions.

At an even higher level it also seems to have worked out for Tierney, Danowski, Zimmerman, Corrigan, Desko just to name a few guys who coached their sons in college
