Ah, yes... I call it the "Hoosiers" ruling...
What the casebook doesn't say, of course, is that there's no requirement for the 5th player to actually have to participate in the game beyond being on the court.
"Coach, you have to have 5 players on the court, but you could just tell one of them to stand in the corner and not do anything"

In addition to the casebook, the rule book has the same note


RULE 3, SECTION 1, ART. 1

Each team consists of five players, one of whom is the captain.

NOTE: A team must begin the game with five players, but if it has no substitutes to replace disqualified or injured players, it must continue with fewer than five. When there is only one player participating for a team, the team shall forfeit the game, unless the referee believes that team has an opportunity to win the game.

Had a JuCo game where one team only dressed 6 or 7 . They got down to 4 players with a minute left and trailing by 3. They sent the game to OT and continued to keep pace before another player fouled out. 5 v. 3 was too much to overcome.

I guess if the team with more than one player gets foul shots, they keep on shooting until they make them or violate.

In the mid-1960s I saw an undefeated boy's VAR team come from 6 points down with 2:30 left in the 4th quarter to win by 2 points, and it did it on the road.

In the mid-1970s I had two women's college games end with one team having only 3 players left on the court.

Not correct. I suggest that you consult the past interps archive.

2003-04 NFHS BASKETBALL RULES INTERPRETATIONS

SITUATION 2: Team A started the game with seven team members in the scorebook. All team members foul out but one, A1. Team A is leading by eight points with 38 seconds left in the game with a chance to win. A1 fouls B2 with Team B in the bonus. A1 occupies one of the first marked lane spaces for the free throw, with no teammate to occupy the other required space. RULING: By rule, a team may continue to play with one player if that team has an opportunity to win the game. Accordingly, since Team A can only put one player in the required free-throw marked lane space, it cannot be penalized. Further, Team B may not occupy the first marked lane space left vacant by Team A. (3-1-1 Note, 8-1-3)

Which is posted on the NFHS website?

You know, for the thousands of basketball officials who do not utilize this or any other social media for officiating guidance.
