To make this list, I was going to have a minimum 70% and 10 years, but opened it up to 65% and 5 years to add more than just 8 Coaches to the list. Information was gathered from a thread that @Lucky#7 and I have been doing. This list is also of current coaches as of last season.

Honorable Mentions (Teams that made the % but not minimum 5+ years)
· Rocky Mountain - C.Culig - 2 Years - 21-3 - 88% - 1 State Championship
· Grangeville – Adams - 2 years - 17-4 - 80%
· Post Falls - B. Bennett - 3 years - 19-10 - 66%
If I were to include this year, ill do it after the season is over, Fruitland's, Ryan Tracy would fall to 75% and Aberdeen's, Duffin would also fall some %. Declo's, Kidd is no longer coaching so he would fall from the list, but West Side's, Moser and Bishop Kelly's, Tim Brennon have only gotten better. With these changes, Tom Harrison would land about #3 on the list.
