FOXBOROUGH — The game doesn’t stop just because he’s on the sideline. So Patrick Chung doesn’t let his mind go to sleep.

In practice, if the reps aren’t his, he mentally makes his play calls from the sideline. On game days, on the snaps he isn’t in, he still gets the calls from the coaches and makes them as if he was. He watches and re-watches game tape. So even if the physical reps he’s getting aren’t the same, the mental ones are.
