Pre-game technical questions

[rfp]

Team A is assessed a technical foul for dunking during warm-ups. We know that any player, even bench personnel, can shoot a technical foul. If bench personnel B-6 attempts the technical free throw, does that make him a starter and therefore subject Team B to an administrative technical for changing starters after the 10 min. mark? If not, why not?

Also, can the five originally designated starters now start the game? If so, what about the "sit-a-tick" rule? Are these simply exceptions?
