even see the "thrusting upwards" leading indicator on that play we are discussing.
the standard had been set that its up to the defender to do something drastic and change normal positioning in order to protect head or neck area of defenseless receiver.
Suddenly in a playoff game is a strange time to change the standard that has been set.
If the new standard is normal tackling is OK even if it includes a headshot, then that's fine but strange time to implement the new standard right in a playoff game.
