The center stage student is usually identifiable on the first day of class. Sometimes the biggest issue with a center stage student is just that Attention. The center stage student can actually be a good thing provided you can keep them focused on one topic. When other students are hesitant to speak up during a class discussion, the center stage student will always be the first one to take part in the discussion which usually eases the other students minds about speaking up. It kind of gets the ball rolling and based on the center stage students comments it brings up other questions they may be reluctant to ask or discuss. So that can be used to an instructors advantage.
