What is the Under Center Offense?

To have an "Under Center" Offense, the quarterback of the team must be directly behind the center. This is to make handoffs easier and runners minimize moving to the left and right.

What are the origins of Under Center Offenses?

This type of offense has been around since the beginnings of football. If you go back and watch a game of football from the 1930's and 1940's you will see that almost every play is under center.

Are there any famous teams who used this defense?

Offenses are slightly different than defenses in how they run their formations, so almost every offense of all time has used this offense. Though, running plays under center was a lot more common 20-30 years ago than it is today.
