I prefer to think that we, as officials at any level, would not concern ourselves with what coaches think or want.
From my NFL contacts, I'm told that the reason they started switching sidelines years ago wasn't a 'coach' driven thing as much as it was driven by sideline officials, to be able to only have to put up with some coaches for one half.
Life will go on, with or without switching sidelines. Get one game under our belts and all will be 'normal.'
