How about some 12 personnel? With those two tight ends being both pass catchers and blockers, the D wouldn't necessarily know which one (or both) is staying in to block and which one is going out on a route.
These guys help diversify the offense for sure. If the Packers can make the run game a consistent threat, that will help the defense by moving the chains and winning time of possession.
