Dallas Center-Grimes forced five turnovers and held South Tama to just 131 yards in a 34-0 rout on Sept. 6.
The Mustangs improved to 2-1 this season and avenged last year’s 26-24 loss to the Trojans that ultimately kept them out of the playoffs.
"This is the one that kept us out of the playoffs a year ago, and to win in the fashion we did was really exciting," DC-G coach Scott Heitland said.
Sophomore defensive back Austin Kloewer nabbed two of the team’s four interceptions and finished with six tackles.
"I think people are seeing why he earned a starting spot last year," Heitland said. "He’s just continuing to demonstrate that he can lead in the ways we need him to. He has a big responsibility on our defense with the position he plays."
Jack Jorgensen and Jacob Lachacz added picks, and Keaton Means recorded a fumble in the team’s first shutout since a 3-0 win over Ballard on Oct. 12, 2012.
The Mustangs held a 24-0 advantage at halftime, scoring on a 20-yard pass from Andrew Kramer to Means with under a minute to play.
"We were hoping to get three," Heitland said. "We got six. That was just icing on the cake.
"Our whole focus in practice was getting points, whether it was three, whether it was six. We need to get points when we get the football."
That preparation paid off. Kramer passed for 149 yards and two touchdowns, including a 4-yarder to Dakota Clausen. He also rushed for a score to put the team on the board in the first quarter.
Running back Chaz Chambers returned from injury to make his first start of the season and ran for a team-high 90 yards on 16 carries, and scored a touchdown in the fourth quarter.
Senior Michael Lortz booted field goals of 41 and 31 yards, and was perfect in four point-after attempts.
Doug Heritage caught seven passes for 63 yards. Means had three catches for 39 yards.
DC-G faces a tough test on Friday with a trip to seventh-ranked Grinnell. The Tigers are 2-1 after a 22-21 loss to then-No. 7 Pella last week.
"Nothing against the three teams we’ve played, but this is by far the best team we will see all year," Heitland said. "Our best defense is going to be our offense. Our offense has to stay on the field."
