Pete Prisco of CBS Sports notes that more and more teams are using a formation he calls the "full-house backfield." Now there's no Olson twins involved or even an unfunny uncle. However, it is a large line-up that brings in the biggest bodies and multiple teams are using it, including the undefeated Packers.
"The Packers use it a lot, usually with a fullback, a tight end and the runner behind the quarterback," writes Prisco. "The Chiefs used it against Miami last Sunday. They lined up Thomas Jones deep behind Matt Cassel with tight end Leonard Pope and fullback Le'Ron McClain lined up split in front of Jones. Those two went into the line to get the linebackers to free up Jones to run. The play got 5 yards on a second-and-4"
For those interested in hearing more about the formation and what offense can do out of it, Old Dominion was practicing from the formation earlier this spring.
