Do pitchers lead with the hip or the foot?

There are many debates in baseball that still rage on today.  One of them involves whether it is better for a pitcher to lead with his front foot or whether he should lead with his hip when he starts his movement towards home plate.  The “foot leaders” camp are often described as advocating the “Drop and Drive” method and the “hipsters” are often seen as advocating the “Stay tall and fall” method. 

In today’s video, I explain my very politically correct answer which is A pitcher leads with both.
