Blocking, RA play, defender in the RA jumps, but does not make an attempt to defend the shot

This is an example of a defensive foul for blocking. The secondary defender is positioned inside the Restricted Area, and while he successfully jumps vertically, he does not make an active attempt to defend the shot. In order for a secondary defender within the Restricted Area to legally defend a shot attempt, the defender must jump vertically while also making an active attempt to defend the shot of the offensive player. On this play, while the defender in the Restricted Area does jump vertically, he does not make an active attempt to defend the shot attempt of the offensive player.
