9-4-3k Horse collar

[ChuckB DuckY]

I don’t have many examples of legal use of HC to differentiate from HCT personal foul.

Notes:

9-4-3k (NEW): The horse-collar tackle has been added to the list of illegal personal contact fouls, regardless of where it occurs on the field.
It is illegal to grasp the inside back or side opening of the collar of the jersey or shoulder pads of the runner and subsequently pull the runner to the ground.

Mbyron:
“1. Let's be careful: a horse collar (grabbing the side or back of the jersey or pads) is NOT illegal. A horse collar tackle is always a foul, wherever it occurs on the field (according to the note on p. 86 of the 2009 rule book)…
(a) B grasps the back or side collar of A's jersey or shoulder pads, and (b) subsequently brings A [backwards] to the ground.”

Situation:
B1 grabs A1, from the side, by the collar with one hand and immediately grabs the waist or chest with the other hand.

According to NFHS can HCT be called?
1) If B1 pulls A1 immediately forward and down
2) If B1 pulls A1 laterally (not down) pivoting/spinning around B1 (initially forward until the spin changes A1s direction backward) and then pulls A1 down and back (A1 is facing backward or his end zone, but is pulled down from behind, but now has not been ‘running’ since his momentum was stopped by B1 and has essentially been a passenger of B1’s spin.
3) B1 spins A1 around and throws A1 back and to the ground violently using A1s momentum against him. Diff PF?
4) B1 pulls A1 immediately forward down and to the side

Answers and explanations would help me clarify this for people more confidently. Thank you in advance.
