I recall that Messignham's offense would often score on the first drive then spin its wheels for a while. He had a decent scripted game, but didn't fare well vs adjustments.
CM was a part of some good ISU scoring efforts here and there, but i always felt it was due in part top the pace of play and possessions. Regardless of all that ISU had an assembly line of QBs that would look great their first few times out there, then level off at mediocre at best. Defense routinely stunk so mediocre QB play wasn't going to get it done.
I think when Mangino took over, ISU ironically enough could never score on their first drive.
