WATCH: Derwin James picks Big Ben’s pocket in game-changing play

Early on, the Pittsburgh Steelers were doing pretty much anything they wanted to on offense against the Los Angeles Chargers on Sunday Night Football. Rookie safety Derwin James changed all that in one fell swoop.

Following a dynamic tackle, James one-upped himself on the next play, intercepting Ben Roethlisberger, who was attempting to hit Vance McDonald near the goal line.

This play was huge. Granted, it was a poor pass from Big Ben, but the rookie pounced all over it and was in great position to make the play, even if it were on the money.

The Chargers got off to a poor start on both sides of the ball. Following a touchdown on offense, they finally made a stop defensively and are suddenly right in this game.
