ISU had the lead late and about to upset and the ISU coach gets a suspect technical late which helped MSU take the lead. If I remember correctly...
That was the NC game that year.
It didn't quite happen that way, but you're not far off. ISU did have a lead on MSU when Tom Izzo got a well-timed technical foul. After that, MSU got the better of the officiating without a doubt. By the time Eustachy got his technical fouls (he got two in one shot to get ejected), the outcome had been decided. ISU was a dangerous #2 seed that year, but the NCAA Committee paired the best #2 with the best #1.
