The 49ers called a total of 1 fire zone blitz the entire game, that I saw. In their first meeting this season, they called many zone concepts and the zone coverages got roasted again and again. There were many more man coverage concepts in this game and, overall, it resulted in a better showing, although Brock and Ward each got beat deep.
Going back a little bit, this is the first possession for ARI.
Mills concept to Palmer's left + a backside deep curl vs Cover 1 blitz. DJ is matched up against Fitz.
5 man rush. Reid comes up to rob the middle, but his real assignment is to cover the RB if the RB leaks out. Brock is in good position to defeat any vertical route from the backside WR by staying in front of him.
Palmer in mid windup, Brock with sticky coverage. All of the DBs on the strongside also playing good man coverage.
Brock is able to contest the throw to force an incompletion. Punt (Ellington fumble).
