I can remember 2x when ISU played at Mackey Arena. Both times ISU won. First time was 1987 when Purdue was #2 and going to be #1 the next day, and ISU beat them 104-96. After beating Purdue in 1987, Purdue then won 19 games in a row and easily won the Big 10. It is still between Michigan and Purdue this year.PU is overrated. But still an impressive win. I can't remember when Iowa won there if ever
