Michaelpr,
The best way to calm your paranoia and to know FOR SURE whether the coach is "bugging" you is to make a comment such as "The coaches wife and I have been having an affair for 2 yrs and the coach is too stupid to know it".
If you get an icy glare, or better yet attacked when you return to the sideline, then you can pretty much be assured that the coach is eavesdropping.
