He didn’t care if his starting quarterback was out. Manhattan head coach Chris Grabowska challenged his team to start Friday’s game fast.

The Tigers responded by securing a stop on defense and scoring early. They went on to win at Sweet Grass County 43-8 in a Southern B matchup.

“We just kept firing on all cylinders,” Grabowska said. “I’m just really proud of our guys for starting fast.”

With starting QB Lane Veltkamp sidelined due to injury, the Tigers (6-0, 4-0 Southern B) turned to Isaac Richardson, who Grabowska felt did well leading the team.

Richardson scored multiple touchdowns on the ground while Garrit Weeda and Toby Veltkamp each scored a rushing TD.

“Isaac had a great week of practice, and he did a good job of running and throwing the ball,” Grabowska said. “The offensive line, their job is to make it easier for whoever is back there. And our O-line did a good job of opening up holes and protecting him in the pass game. … I think our O-line is pretty exceptional.”

The Tigers thrived on defense again as well. Manhattan’s Gabriel Delgatty scored a touchdown on an interception return, and the Tigers finished the night with six forced turnovers.

“Defensively we played really well,” Grabowska said. “It’s been a strength of our team for a couple of years, and tonight was no exception.”

Grabowska felt expectations were high going into the season. He thought starting 6-0 was possible. He’s confident in his offense no matter who’s at quarterback.

And he’s confident next week going into Manhattan’s home game against Broadwater County, which was also undefeated in the conference going into Friday.

“Townsend’s always a tough opponent,” Grabowska said. “It’s going to come down to who’s going to execute the best and who’s going to prepare the week of. We’ve got to slow down their pass game, and we’ve just got to execute on all phases of the game.”
