North Dakota was playing North Dakota State in the annual battle for the Nickel Trophy on Oct. 17, 1998. The nation's best Division II conference, the North Central, had not yet been destroyed. There was a sellout crowd of 19,006 packed into the Fargodome.
Randy Hedberg was North Dakota's offensive coordinator.
"I was in the press box calling plays," he said. "And it was so loud in there that I couldn't hear on the headset what they were trying to say to me from the sideline."
The Sioux built a 22-3 halftime lead, and then NDSU exploded for three third-period touchdowns to take a 25-22 lead. A North Dakota field goal put the score at 25-25 entering the fourth period.
"We were down in our end and flexed out Jimmy as a wide receiver," Hedberg said. "Then, we ran a little screen look and sent Jimmy on a slant. The quarterback [Sean Greenwaldt] hit him in stride."
Jimmy was Kleinsasser, the senior tight end from Carrington, N.D. And the play covered 77 yards for a touchdown that sent the Sioux to a 39-25 victory.
"He was maybe 260 [pounds] then, and he took that slant and just ran away from people," Hedberg said. "Everyone knows him as big and strong, but he was fast.
"Bob Babich, now the D-coordinator with the Bears, was the NDSU coach. And I remember seeing a quote from him after the game that the one play probably put Jimmy into the first two rounds of the NFL draft."
