substitution or deception?

[Mike L]

Answering "no it's not" or "no, it's ok" is argumentative and I don't think you should be engaging in any arguments. It's a little better to head the problem off and not give them the opportunity to say or do something stupid by answering the original question better. I've had the same comment from players and coaches, to which a simple "that's a college rule, not a high school rule" (except for you crazies in TX & MA). 99.9% of the time that brings the "debate" to a close without having to whack someone 15 yards.
