If you caught Saturday’s matchup between the University of Michigan and the University of Wisconsin, you may have seen something a little bit strange from the Wolverines.

Coach Jim Harbaugh got people talking when the team lined in what’s called the “train formation” – and it came from none other than Chatfield High School.

Jim Harbaugh said Michigan assistant Jay Harbaugh was pouring over high school footage – and saw game tape of tight end Dalton Keene. They saw Chatfield’s formation, and the rest is history.

Chatfield coach Bret McGatlin confirmed that’s what happened on Twitter on Saturday.

According to Chsaanow.com, Chatfield calls the play the Speed Line – and typically runs it a few times a day. It’s part of what they call the Psycho offense, which is designed to not allow the defense to make pre-play adjustments.

It was the brainchild of McGatlin’s dad.
