You need to check the definition of a technical foul in 4-17. You will see that part of the wording is "a foul by a non-player" or something similar.
Therefore, such a foul would have to be a technical foul.

I don't believe so. The basis of the NFHS ruling was that only one technical foul was not enough to compensate the offended team for being deprived of the three-point attempt since they could only score two points from the ensuing free throws, thus two technicals and four FTs were required for fairness. That would not be the case on a two-point attempt.

No, the definition of a player is one of the five team members LEGALLY on the court during playing time. A team member entering illegally wouldn't meet that standard.

What you are referring to is the provision that makes a team member a legal player once the ball becomes live, if there had been some sort of illegal substitution during a dead ball period.

It is two very different situations and 3-3-3 is only applicable to the latter.

It's definitely not written for this situation, and the way it's written leaves some potential holes, IMO.

Situation 1:
Official counts 5 for each team and administers the throw-in. After about 30 seconds of action, A6 commits a PC/charging foul.

Table informs the official that A6 had entered during live play immediately prior to receiving the pass.

Was he a legal player? What sort of foul do you charge?

Not a legal player as each team may only have FIVE legal players at any one time. So this is a technical foul. I would ignore the play itself and simply charge the team T for having more than five team members participating.

BTW that very rule and T demonstrates the inability of trying to apply your citation to such situations. If the ball of dead for a throw-in and then play was restarted with one team having six on the court, your citation would make them all legal players. That cannot be the case.

Okay, let's assume A5 leaves the court and sits on the bench because he happened to be closest to the bench and realized A6 had come onto the court. When, if ever, does A6 become legal?

Or, an alternative.

Following a multiple substitution, the official miscounts and A begins the play with 4 players. A6 jumps in mid-play, catches the pass, and runs over B1. As the official reports the PC foul, the table informs him that A6 did not enter legally. Was A6 ever a legal player?

So if A6 had scored a basket during the timeframe and then on the ensuing throw-in committed a foul you would do exactly what when you discover/are informed that A6 is an illegal 6th player?

Okay, so you guys are going to make me actually think about these scenarios. Fine. I'll ponder the situations for a few hours and then post my final thoughts.

Right now, I'm leaning towards any points scored count and penalizing not only the team with a T for more than five participating (or an illegal substitution T to a particular individual, if appropriate for the circumstances) AND penalizing any contact fouls by a non-player as technical fouls to that individual.

Until then...shut up. ;)

Ok, I have become convinced that both a team technical foul and an individual technical foul are appropriate if there are six in the game and the sixth man makes a contact foul.
Any points scored or time consumed prior to the official recognizing the problem must count as normal.

If A5 departs during live play and A6 enters, then that situation is handled differently. There must be an individual T to the illegally entering substitute and a 2nd one to A6 if he fouls during the ensuing action. Yes, that would DQ him. Harsh, but this isn't hockey. Teams can't sub during live play.

Wow.
