Here the niners used play action to suck the linebackers up, the Seachickens were in man cover-1, meaning they were playing man coverage with a single high safety over the top. When Kap turns around he looks toward Crabtree who is running a shallow comeback with Boldin running a Hitch from the slot. Cam Chancellor is playing with outside leverage on Davis. When Kap turns around He see's the man coverage on Crabtree.Kaep keeps looking Crabs way, looking for him to uncover, Thomas-the high safety, jumps on the inside of Boldin with #40 playing man on the outside of Boldin, essentially double teaming Anquan. Sherman had a flat foot cover on Crabs - meaning he didn't backpeddle much on Crabtree looking to jump the comback.Kaep has room to step up in the pocket(highlighted with the O) the line did a great job. When he saw the man coverage read he should've automatically moved to Vernon knowing Vernon was running a Deep In(or DIG) route with the safety playing outside. You can see the seperation Vernon gets on Chancellor.Finally, you see Kaep didn't step up into the pocket, instead, he scrambles out right and throws to Crabs(who did make a spectacular 4 yd catch) It was the play that looked like Crabs may have not gotten his 2nd foot in bounds but Seattle never challenged.) As you can see Vernon is wide open if Kaep moves through his progression and recognizes the outside leverage pre-snap. It was a 4 yd gain but could've been a 12-plus yd gain.Kaepernick was later intercepted on this drive(which I will show next), He missed a couple plays like this in the game. Could've been a bigger win for us. But still a good win nonetheless and Kaep did play a pretty good game.
