Basically, they brought a safety into the box on the side of the formation where Hifo was lined up. Then when Hifo went in motion, that safety bailed, and the other safety ran up to the line of scrimmage where Hifo was headed.

It was pretty effective shutting down the jet sweep, but Squally's big run in the second half was a direct result of that safety crashing down on the line of scrimmage. He took himself completely out of the play.

I wonder if other teams will try that same strategy or not.
