Substitutes Following Technical Foul

[Bad Zebra]

Does anyone have a rule (or case book) reference for allowing substitutes in following a technical foul? 3-3-1C specifically mentions when subs are allowed for PERSONAL FOULS.

Since a substitute may enter to shoot FT's for a T, would it follow that ANY subs should be beckoned prior to the first, prior to the second, or prior to the throw in at mid-court? It would make sense to allow ANY subs prior to the first FT as that would be a good time for a coach to get a hot-head off the court following an unsporting T.

Had this come up in a Boys V game last night and I don't think we handled it properly. We didn't allow subs until AFTER the second FT because none of them were coming in to shoot FT's and none were replacing a hot-head.
