With no former training? No. We have a ~130lb purple belt at our gym who every time a new gym bro would drop in for a class our instructor will have him roll with her. Usually, she taps them 3-4 times in a 5 minute roll. It's a good way to weed out ego fags because if you can't take a whooping on your first class you likely won't last very long anyways because your ego gets in the way. Conversely, level headed people get humbled, see the "magic" at work, and get hooked immediately.
