Putting less than seven players on the line of scrimmage is going to result in an illegal formation penalty. The defense can put as many players as they want on the line of scrimmage. On PATs, field goals and punts the defense is not allowed to place more than six defenders on one side of the snapper.
I may be wrong but I think there were 7 on the blocking side.
