Ask coach if he wants a time-out on a made basket?

[Jeremy Hohn]

I was just curious your thoughts on this practice. I use it quite often for a trailing team if the game is close and they are trying to close the gap. I ask the coach if he would like me to grant a time out on a made basket. That way you don't lose time trying to recognize the time-out, or, in my case tonight in my high school game, you have a real soft spoken coach that can't get himself heard above the crowd noise.
It worked well for me tonight, and has other times before.....

...thoughts? Is there anything in the NF rulebook to address this practice? Just curious what you guys think...
