I honestly think it is better to start off coaching at an unknown college/high school since you won't have that added pressure if you are just starting off your coaching career. If you already have some coaching experience under your belt and want to put your skills to the test, I say do a graduate assistant position for a college team before going international. BUT if the opportunity presents itself, I would say go for it. Big or small, put your knowledge to the test.
