Slappin' Glass sits down this week with Coach Stefan Grassegger, current Austrian NT Assistant and former Euroleague Assistant. The trio dive into Coach Grassegger's doctoral studies on mental health in athletes and coaches, building a defensive shell, backside defensive rotations, guarding great PNR passers, limiting turnovers, and much more.
