I looked at the three DII teams in Rupp, all of which are human-coached. There are 13 Hawaiians on the rosters. The other players are from all over, with only California and Connecticut having multiple signings.
In Naismith, with only one human coach, he has 8 local boys, 1 from California, and 3 internationals.
I don't think there's any way you can compete for the top players from the mainland. I'd go for the top local boys, take a chance on some internationals, and look at the mainlanders on the morning of signing day.. By then, most of the mainland coaches will have sewed up their choices and you'll have less competition for the 'best of the rest'.
