On Oct. 15, 1983, Iowa State recorded the school’s last victory over Big 12 conference rival Colorado by defeating the Buffaloes 22-10 at Cyclone Stadium.

Versatile Cyclone fullback Jason Jacobs keyed the Cyclone victory with 144 all-purpose yards and two touchdowns. He provided the initial spark for the ISU offense early in the first quarter when he took a swing pass from Cyclone quarterback David Archer and rambled 64 yards down the sidelines to give ISU an early 7-0 advantage.

“He was very close to going out of bounds,” Cyclone head coach Jim Criner said of Jacobs’ electrifying reception. “I was hoping someone would clip an official so he wouldn’t see it.”

After a 26-yard field goal by Tom Field pulled Colorado within 7-3 early in the second quarter, Jacobs came through for ISU once again. This time, he did his damage on the ground, sparking a 15-play, 81-yard scoring drive with consecutive runs of 17 and 19 yards.

“I’d like to be known as a versatile player — running, catching and blocking,” Jacobs said.

Jacobs completed the drive with a one-yard scoring plunge to increase the Cyclone lead to 13-3 after ISU place kicker Marc Bachrodt missed the point after conversion.

Colorado managed to respond with an 80-yard scoring drive of its own, capped off by a 34-yard touchdown run by Buffalo wingback Ron Brown on a reverse to cut the deficit to 13-10.

Iowa State was determined to end the half on a high note, however, and with 34 seconds remaining, Cyclone quarterback David Archer hit flanker Dan Gantt with a 14-yard scoring strike to put ISU on top 19-10.

After a first half full of offensive explosives, the next 30 minutes were a defensive struggle for both squads. Colorado was able to hold Jacobs, Archer and company to a 19-yard Bachrodt field goal with just over two minutes remaining in the game for its only second half points.

The Cyclone defense, however, was even more impressive as it utilized its quickness to shut out the Buffaloes and preserve the victory.

“I think we were relaxed after we got the lead,” Criner said. “Our defense had the courage to keep us in the game. Today was not a great football game, but it was a win.”

ISU edged Colorado in total offense, compiling 333 yards to the Buffaloes’ 301. Archer completed 19 of 31 passes for 200 yards and two touchdowns, while Jacobs paced the ISU rushers and receivers with 69 yards rushing on 15 carries and 75 receiving yards on five receptions.

The victory was the second straight for ISU, which raised its record to 2-0 in Big Eight conference play and 3-3 overall.
