IMO...
1. Mark "Doc" Mugiishi (Iolani) - 5 consecutive titles from 2002-2006 is a dynasty although they did have some talent. Doc identifies his team's strengths and weaknesses and plays to both. There are 6-7 assistants on the bench, most former players, others have been with Doc for over 15 years. Not many other programs state wide has the type of continuity.
2. Kelly Grant (Kaimuki) - When the Bulldogs won their state title in 2007, it solidified Grant what most have thought for years, Coach Grant not only can motivate but he is a very good gametime coach. Players love this guy.
3. Chico Furtado (Kalaheo) - When Coach Smith passed away it was a logical choice for longtime assistant, Coach Furtado to step in. The Mustangs did not miss a beat. Intense and driven, he gets the most out of his players every year. Players don't just transfer to Kalaheo to take French.
4. Nelson Wong (Kamehameha-Hawaii) - Consistant. Consistant on sideline, consistant teaching of his system. In an 'one and done' tournament, such as states, consistancy pays off. Coach Wong's teams aren't the most talented but they are able to compete with anyone.
5. Greg Tacon (Moanalua) - A few seasons ago, Coach Tacon was let go from Punahou and replaced with an alum. Since his former employer seems to be focused more on winning..sorry I mean competing..their loss in Moanalua's gain. (Now hear me out..if you recruit..wait said the 'r' word..I mean if athletes just so happen to go to your school..which academically is one of the top college prep schools in the nation but for some strange reason can't qualify to play in their freshmen year of college..that's just competing right?!) Coach Tacon is a solid teacher and tactician. He also excels at making gametime decisions. There is now more to OIA basketball then just Kalaheo.
6. Dan Hale (Punahou) - All I hear are negatives regarding Coach Hale's decision making, coaching style but how can you argue with a state title. As an observer, he does an good job managing his talent. There are always expectations and pressure, fair or unfair, at Punahou. Its state title or bust. How many coaches could coach under that type of pressure?
7. Harry Scanlan-Leite (St. Joseph) - If you want a clinic on how to get the most out of your roster, head over to this small campus in Hilo. No one does a better job with less talent in the state. His teams are always competitive and are the best at running the disciplined Princeton-style offense.
8. Hiram Akina (Mililani) - Whether its an 1-3-1 zone, 3 point barrage, run-and-gun or full court trap, Coach Akina has seen and implemented it all. A veteran coach who has adapted to today's game and today's athletes. The Trojans are lucky to have him.
9. Jesse Nakanishi (Kamehameha-Kapalama) - The knock on Coach Nakanishi has always been the lack of maturity in games. However, I have seen tremendous growth in the past couple of seasons. Players respect him which isn't always an easy thing for a young coach. His X's/O's have vastly improved as well.
10. Bob Morikuni (McKinley) - Not only one of the nice guys in high school basketball but he can coach as well. He takes raw athletes, simplifies the game and makes them good basketball players. Players play and respect him which has been difficult for former coaches at this school.
Others of note -
Donald Awa (Konawaena)
Don Fernandez (Kohala)
Allan Silva (Farrington)
