I coached a 5'5 PG who was our best post player for 2 reasons; 1, he worked at it to be good with his moves, 2, rarely did he encounter a defender who was used to defending the post. He'd post up bigger guards and get them in foul trouble because they weren't comfortable. If they switched, he'd take them outside and dribble by them. Point is, versatile skill set works both ways. The pendulum has swung so that all bigs can play on the perimeter, time to take it back and get more balance.
