at the 45:08 mark on this video, you can see the play
https://texags.com/forums/5/topics/3502644on the blindside block call, walker is 3 yards in front of the DB, coming from the side where the play is. how in the world is that "initiated from outside the opponent's field of vision, or otherwise in such a manner that the opponent cannot reasonably defend himself"?
bad call IMO.
but on the targeting, once that blindside call is made (which was wrong), the DB is a "Defenseless player." and the hit did meet the markers to be targeting IMO.
tldr, not a blindside block, so also not targeting
