In the Rams' final drive at the end of the game, the Lions pulled all of their starters on the defensive line - Sammie Hill and Andre Fluellen were the tackles and linebackers Julian Peterson and Zack Follett dropped down to play defensive end (Turk McBride had sprained his ankle earlier in the game).
A lot has been made, in the press anyhow, of the offense finally getting to wrap up a game with the victory formation. It turns out the Defense did the same thing prior to the lions getting the ball back for our offense. JP and Zack as ends, wish I could remember that.
