In fact, what Wisconsin is doing is anti "scheeming". As more and more teams move towards the spread, the more defenses adapt. As a result, offenses like Wisconsin's and Stanford's can be very successful. Ohio State has this problem. The OSU defense has fully adapted to defend the spread, but what gives them trouble is MANBALL. I also think you see it with Big 12 defenses, which all need to stop the spread. When paired up against physical running teams like Illinois and Iowa, they had issues.
Point is, this year's MANBALL is next year's spread n' shread (and vice versa).
