Like just about every school in the nation, ISU does not have a men's gymnastics team.
Men's Gymnastics is nearly a dead sport wrt NCAA - 5 Big Ten programs, a few out west (but none of the new Big Ten west coast programs), and the service academies. That's it. If you put them all together, they wouldn't make up one decent conference.
Back in the day (70s? 80s?) just about every Big Ten school had men's gymnastics.
Indiana, Wisconsin, Michigan State all dropped it over the last 20 years or so. Iowa and Minnesota dropped it just a few years ago.
In recent years, Big Ten men's gymnastics has become basically Michigan - with the other handful of schools contesting 2nd through 5th places.
