Tripping

Correct Call:	No call. The black team’s player falls down, but does not create the trip. What creates the trip is the white team’s player running into the downed player.
For this to be a penalty:	There would need to be a flagrant/purposeful act to get the white player to trip.
Game Level:	This should be called at every level.

Correct Call:	Tripping. 1 minute personal foul. This one is nuanced. Because the defender’s check first lands on the shoulder and never contacts the stick, and then trips the player, this should be tripping.
For this to not be a penalty:	The initial check needs to get stick first. If he gets stick first, and the follow through ends up tripping the offensive player. No foul.
Game Level:	This should be called at all levels.
