team subs free throw shooter question

[lpbreeze]

Just looking for some examples when a team is allowed to pick the free throw shooter.
If a player who is supposed to shoot two free throws and can't because of injury who picks?

I was thinking back as a player and remember a couple of times when the opposing coach picked a player off our bench to shoot the free throws but I can't remember why.
If the free throw shooter gets a technical at the line before two fts or after the first shot, do you shoot the tech fts and then shoot the remainder fts or are they canceled? If the player got a tech before the free throws and it was his fifth foul would they still be shot and who picks the shooter. Same with a false double foul and if it was the shooters fifth foul but he has two shots to shoot.

--------- man, i hate fruitcake unless its done right.
