Marmion traveled to Ottawa for its second football game this season.
But the expected showdown never materialized as the host Pirates, a Class 6A state quarterfinalist last season, were decimated by graduation losses.
Marmion quarterback Brock Krueger was 7-for-11 passing with a score, and sophomore fullback Lucas Warren scored a pair of rushing touchdowns as the Cadets stormed past Ottawa 45-0 Friday night.
"We played very, very well," Marmion coach Dan Thorpe said. "Brock Krueger was able to escape the Ottawa rush several times and made excellent throws."
Krueger connected with Josh Meyers from 33 yards out in the opening quarter for what would prove to be the only points Marmion (2-0) would need.
Riley Demoss' 30-yard field goal gave Marmion a double-digit lead entering the second quarter, and Warren had the first of his two scores from 7 yards out.
Mike Montalbano carried only four times, but his 64 yards complemented the inside Warren attack.
Montalbano upped the Marmion spread to 24-0 in the second quarter with a 9-yard TD run, and Thorpe said the game swung forever for his squad in the waning moments before the intermission.
"We had a great goal-line stand right before halftime that was very crucial," Thorpe said.
Lucas, who led the Cadets' rushing attack with 68 yards on 11 carries, gave Marmion an insurmountable 30-0 lead with an 18-yard gallop early in the third quarter.
Demoss was perfect on the night with six conversions, plus his first-quarter field goal.
Reserve running back Mitch Feltz closed out the Cadets' scoring, bulling in from a yard out in the third quarter.
Feltz finished with 46 yards on 13 carries, and his second score -- also from a yard away -- instituted a running clock.
"We had running back-by-committee tonight," Thorpe said.
