Going back a bit. Here is the first pick6.
This is a pick a side play that puts in beaters to the two coverages Kap sees the most.
Left side: Cover3 beater. If this was cover3, the orange drag route pulls the underneath defenders towards the middle of the field to get a throwing lane for the red Curl. The red Curl (Torrey) pushes the deep 1/3 back, then curls.
Right side: Cover1 beater (Fade/Out concept). The 49ers have executed this combination many times versus ARI. If I know it, ARI knows it. To come out of the gate, on the first '3rd and pass it' situation and call this concept is a bit arrogant. Come on Geep, you don't think ARi studies and knows what has worked against them?
versus Cover 1 blitz
Kap takes the snap and properly looks to his right towards the fade/out. In this pic, he has completed his dropback, but for whatever reason, doesn't want to pull the trigger. When Kap sees the CB's back turned to the play (Patton's CB), that should tell Kap that the area along the sideline is open for targeting.
Kap takes a slight shuffle step, then decides to throw, by then it's too late. With VD running an Out pattern, not his specialty because any route consisting of a 90 degree cut is not VD's specialty, the DB breaks on the route.
To the endzone camera to see why the throw had little velocity. Triple A gap blitz. The NT slants to Martin's right shoulder to create space. Two defenders (red, yellow) fill the space.
This is Kap with his dropback completed. His footwork is good and he is in a throwing position. He's looking right at VD. Hyde is facing a 2v1. If Kap starts his throwing motion now, he should release the ball in time. At this moment in time, the DB over the top of VD is still in his backpeddle (not shown).
Instead, Kap takes a slight shuffle step to get his front foot out of position. He moves that front foot (left) towards the middle of the field, away from where VD is. A QB wants to point his toes towards where he throws. This shuffle step is counter productive.
Notice the hop step that gets his left foot out of position.
Easy pickings. If Kap throws this as soon as his drop back is completed, the pass is thrown with anticipation (before VD breaks), and with velocity, because Kap can step into his throw.
