The permutations, Wooten said, were "really messy".
A must-win would have put them on top of their pool and Onehunga second, provided Mt Albert had beaten Otago Boys' High but to no avail.
However, HBHS are tanked up in self-belief going into the match against Rangitoto who boast Tall Black Tai Wynard.
"It'll definitely be a David versus Goliath ... but we see ourselves as the best smallest school in the country," he said, reflecting on how HBHS two years ago beat No1 Rosmini School (Auckland) as well as came within seconds of upsetting Westlake College.
HBHS, according to Wooten, have only once got to a top-four finish during his tenure at the school.
"In the school's history we've only done it twice and I think the first time was in the late 1970 or early 80s."
He lauded his boys for their 70-56 victory over Mt Albert Grammar after issuing a 50-28 statement at halftime.
Co-skipper Mataeus Marsh scored 26 points and Isaiah Jones-Mitchell added 18.
Lose this morning and HBHS will play off for 5th-8th in the country.
