The reason for this is important tho - the reason we play scared is that it is VERY SCARY TO PLAY OFFENSE WITH NO PLAYMAKERS. A bunch of guys who are not built to make plays are constantly under pressure to exceed their capabilities, leading to predictable bad plays and therefore a diminishing return on confidence. No guards means no swagger.
Look at our most swaggeriffic teams - they all had 2+ guards who could absolutely razzle dazzle with the ball and make things happen.
Kemba/AJ, Bazz/Boat, Taliek/Ben, El-Amin/Ricky Moore
Its why guards/playmakers are such an outsized influence in march madness. If every pass and entry and everything is hard on offense, it saps free flowing confidence and shooting and easy buckets. Everyone knows they can't make mistakes, and it just makes teams play tight and weak.
