re: Is this not the definition of targeting?

Probably. The TV copy showed the sideline over and over (trying to see if stet stepped out of bounds which was an awful call on the field).

When the announcers and booth ref were discussing targeting, they showed the tight angle and the booth ref properly predicted from that angle that no penalty would be given.

So yes. The OP should have known better (sideline angle is misleading because it doesn't show where contact was mostly made)
