Are six team members on Team A participating? What's the call?

If the ball is dead, the throw-in hasn't started yet, has it? isn't it also a substitution opportunity?

Why wouldn't you just get the extra player off, just like you're supposed to do on any other throw-in before letting the ball become live?

If you're going to look for reasons why the play is illegal, why not also maybe look for reasons why the play is legal?
