You certainly have a defenseless receiver, but you don’t have an “indicator.” See Rule 9, Article 4 (pg 96).

In this tackle, there is:

• no launch (defender doesn't leave his feet)
• no crouch followed by an upward and forward thrust 
• no lowering of the head to make forcible contact with the crown of the helmet (watch all the angles; contact is much nearer the facemask than the 6 in circle from the top of the defender’s helmet)

As for the last suggested indicator, I have a hard time watching that play and coming to the conclusion that the defender is "leading with helmet... to attack with forcible contact the head and neck area" of the WR. The DB breaks on the ball and, when he gets there, wraps up and follows through. Given the form tackle and the fact that the WR's body and head are turning so quickly, it's hard to argue that the defender is leading with the helmet for the purpose of attacking the head and neck area (instead of, say, trying to get there quickly and make a form tackle). It's a judgement call, but not one that is obviously right or wrong. 

A lot of people don't understand targeting and assume that any helmet to helmet contact is automatically targeting. It wouldn't be the first time SVP has been wrong. 

And as far as you're concerned... I wouldn't trust the opinion of a UT fan on a OU game either 😂
