The theory of the "isolation" run in football is that the up-front blockers will leave a linebacker in a position where he has to make the tackle, and then a fullback will lead the tailback into that area.
Glen Mason was the offensive coordinator and line coach at Ohio State for Earle Bruce in the 1980s. "We were an isolation team — I-formation, two backs in the backfield and we pounded 'em," Mason said. "For the most part, the Buckeyes had the type of athletes to do that."
Mason was in his 30s and preparing for a chance to be a head coach.
"I did some studying of teams nationally and saw that if you couldn't run the ball and play good defense, you were losing," he said. "Quite a few teams were throwing the ball all over and putting up some big numbers, but they weren't winning."
Mason went to Kent State in 1986, put in the wishbone and went 12-10 in two seasons with the previously downtrodden program. That landed him at Kansas, where Mason took the Jayhawks from 1-10 in 1988 to 8-4 with an Aloha Bowl victory in 1992, and then to 10-2 with another Aloha Bowl victory in 1995.
"We started with a run 'n' shoot with a running flavor at Kansas," Mason said. "We evolved into a zone running team."
Mason was hired by the Gophers on Dec. 14, 1996. And he was inheriting the exact scenario he identified a decade earlier: a Big Ten program that had thrown the ball all over and put up some big numbers with coach Jim Wacker, and could not win.
The Gophers were 8-15 overall in Mason's first two seasons. It took some time to round up the mobile linemen who could make the zone-blocking scheme work — who could pull to the point of attack and create double teams.
