Re: The improbable improvement of Kareem Jackson
On the ball that Sanchez had to throw away, the receiver Schillen ran a swirl route.
Jackson was in one-on-one with Schillen, no safety help.
Schillen ran 10 yards and worked to the inside hard before cutting back toward the corner.
Had Jackson turned his head (it would have been to the inside), he would have lost the receiver when he cut back toward the corner.
All Jackson had to do is what he did: To pin the receiver to the end line and push him out of bound when the ball comes (with the change in rule that came out a few years ago, the CB can push the receiver out of bound once the ball is in his hands.) If the receiver doesn't have both feet in bound, it's an incompletion. Simple but efficient strategy by Jackson here.
