sub for shooter

[rgaudreau]

Here's my sitch.

Senior boys game.

We're shooting 2 free throws following a foult.

After the 2nd shot, (shot goes in), coach calls for a sub for the shooter. B1 already has possession of the ball for a throw-in. I refused the substitution, because I thought coach should have called it before the shooter had possesion of the ball for FT. Basically, I said "too late coach, next dead ball".

Was I right in this situation? NFHS rules please.
