timeout when a player fouls out

[rocky]

okay I know i am a coach and i should stay out of you officials and your discussions but here is a question-- did you notice more teams are using the time to get a replacement into the game as a timeout?? will not this lead to longer games or do i worry about the little things to much, and also in the movie Hoosiers he never replaced a disqualified player "my team is on the floor" does he have to if he has avaialable players? just a thought thanks
